Diode

Diode   What is diodes explain- A diodes is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.BY www.ledihatv.com What is diodes and types? A diode is a two terminal electrical device. Diodes are made from a semiconductor, most often silicon but sometimes germanium. There are various types of diodes, but the ones being discussed here are Zener, Rectifier, Schottky, Transient Voltage Suppressor, Thyristor, Silicon Controlled Rectifier, and TRIAC. BY www.ledihatv.com   Why are diodes used? Diodes are used in circuit protection due to their ability to restrict electrical current to flow in only one direction. This trait is useful because some electrical components and devices will be damaged or malfunction if current flows in the wrong direction. BY www.ledihatv.com Is diode convert AC to DC? The diodes allows the current to pass only in one direction. If the diodes are used in AC it will conduct only during half of the cycle. Thus they are used in the conversion of AC into DC. Hence, diodes are DC. What Is a Diodes? Diodes are used to protect circuits by limiting the voltage and to also transform AC into DC. Semiconductors like silicon and germanium are used to make the most of the diodes. Even though they transmit current in a single direction, the way with which they transmit differs. There are different kinds of diodes and each type has its own applications. BY www.ledihatv.com Diodes Symbol A standard diodes symbol is represented as above. In the above diagram, we can see that there are two terminals that are known as anode and cathode. The arrowhead is the anode that represents the direction of the conventional current flow in the forward biased condition. The other end is the cathode. Diodes Construction Diodes can be made of either of the two semiconductor materials, silicon and germanium. When the anode voltage is more positive than the cathode voltage, the diodes is said to be forward-biased, and it conducts readily with a relatively low-voltage drop. Likewise, when the cathode voltage is more positive than the anode, the diodes is said to be reverse-biased. The arrow in the diodes symbol represents the direction of conventional current flow when the diodes conducts. This article lets you understand in detail about various types of diodes. Diodes:-Types Light Emitting Diodes Laser diodes Avalanche diodes Zener diodes Schottky diodes Photodiodes PN junction diodes Light Emitting Diodes (LED) When an electric current between the electrodes passes through this diodes, light is produced. In other words, light is generated when a sufficient amount of forwarding current passes through it. In many diodes, this light generated is not visible as there are frequency levels that do not allow visibility. LEDs are available in different colours. There are tricolour LEDs that can emit three colours at a time. Light colour depends on the energy gap of the semiconductor used. Laser Diodes It is a different type of diode as it produces coherent light. It is highly used in CD drives, DVDs and laser devices. These are costly when compared to LEDs and are cheaper when compared to other laser generators. Limited life is the only drawback of these diodes. Avalanche Diodes This diode belongs tso a reverse bias type and operates using the avalanche effect. When voltage drop is constant and is independent of current, the breakdown of avalanche takes place. They exhibit high levels of sensitivity and hence are used for photo detection. Zener Diodes It is the most useful type of diode as it can provide a stable reference voltage. These are operated in reverse bias and break down on the arrival of a certain voltage. If current passing through the resistor is limited, a stable voltage is generated. Zener diodes are widely used in power supplies to provide a reference voltage. Schottky Diodes It has a lower forward voltage than other silicon PN junction diodes. The drop will be seen where there is low current and at that stage, voltage ranges between 0.15 and 0.4 volts. These are constructed differently in order to obtain that performance. Schottky diodes are highly used in rectifier applications. Photodiodes A photo-diode can identify even a small amount of current flow resulting from the light. These are very helpful in the detection of the light. This is a reverse bias diode and used in solar cells and photometers. They are even used to generate electricity. P-N Junction Diode The P-N junction diode is also known as rectifier diodes. These diodes are used for the rectification process and are made up of semiconductor material. The P-N junction diode includes two layers of semiconductors. One layer of the semiconductor material is doped with P-type material and the other layer with N-type material. The combination of these both P and N-type layers form a junction known as the P-N junction. Hence, the name P-N junction diode. Diode P-N junction diode allows the current to flow in the forward direction and blocks the flow of current in the reverse direction. Related Articles: How do Diodes Work as a Rectifier?

If AC is window, our pro remove the AC and clean the AC in bathroom with water. Urban Ac Service Mumbai What is wet service vs dry service? Difference Between Wet Cleaning vs Dry Cleaning The most important difference between wet cleaning and dry cleaning when it comes to professional cleaners is the use of non-water solvents in “dry” cleaning and the use of chemical-free water-based cleaning agents or solvents in “wet cleaning. How much split AC installation charges in Mumbai? On an average, ac installation costs ₹999.0. However, ac installation price varies with your requirements and needs. On the lower end, professionals generally charge between ₹599.0 and ₹649.0, and the higher end prices can range from ₹1499.0 to ₹1999.0, Urban Ac Service Mumbai Can I run AC without servicing? Although the mechanical parts of the AC will work, the cooling power will be lost and then the system will start to sustain serious damages. These damages will result in higher costs of repairing or even replacement of some parts, How many times AC should be serviced? Even without noticeable defects, we recommend getting an air conditioner checked at least once a year to ensure it’s performing at its best. Here are the signs to be on the lookout for that may indicate an air conditioner needs immediate maintenance. If your unit makes more noise than usual, the filters may be clogged. Urban Ac Service Mumbai Is it necessary to service AC every year? While it’s always a good idea to do some regular check-ins and cleaning throughout the year to make sure your system is running smoothly, a once-annual air conditioner service appointment is always essential. What is AC dry charge? DRY-CHARGED UNIT. An air conditioner or heat pump that is shipped dry and charged with refrigerant at the place of installation. Dry-charged units are appropriate for homeowners who need a replacement unit compatible with R-22 refrigerant. What is the disadvantage of wet cleaning? Is dry clean done without water? Instead of using water and detergents, environmentally friendly solvents, such as hydrocarbon, are used to clean the clothing. No water is used in this cleaning process, hence the name “dry cleaning.” In this method, clothes are placed in a large machine with the solvent to remove stains and clean the clothes.06-Mar-2018, Urban Ac Service Mumbai Is dry cleaning better than water? Dry cleaning is also a gentler process than washing, meaning it’s less likely to damage delicate fabrics. If you want to keep your clothes looking great for longer, dry cleaning is the way to go. Dry-cleaned garments are less likely to shrink or develop wrinkles than those that are washed and need ironing afterwards.

air conditioner Split ac Any queries please contact 7770074243 Air conditioner, Split ac .often abbreviated as A/C (US), AC (US), or air con (UK),is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as “comfort cooling”) and air conditioner in some cases also strictly controlling the humidity of internal air. Air conditioner can be achieved using a mechanical ‘air conditioner’ or alternatively a variety of other methods, including passive cooling or ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). Air conditioner Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them to heat and also cool an enclosed space. Split ac in, which typically use vapor-compression refrigeration, range in size from small units used within vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming increasingly common in cooler climates. Split ac air conditioner According to the International Energy Agency (IEA), as of 2018, 1.6 billion air conditioning units were installed, which accounted for an estimated 20% of electricity usage in buildings globally with the number expected to grow to 5.6 billion by 2050. The United Nations called for the technology to be made more sustainable to mitigate climate change and for the use of alternatives, like passive cooling, evaporative cooling, selective shading, windcatchers, and better thermal insulation. CFC and HCFC refrigerants such as R-12 and R-22, respectively, used within air conditioners have caused damage to the ozone layer,and HFC refrigerants such as R-410a and R-404a, which were designed to replace CFCs and HCFCs, are instead exacerbating climate change. Both issues happen due to the venting of refrigerant to the atmosphere, such as during repairs. HFO refrigerants, used in some if not most new equipment, solve both issues with an ozone damage potential (ODP) of zero and a much lower global warming potential (GWP) in the single or double digits vs. the three or four digits of HFCs. Split ac History Air conditioning dates back to prehistory. Ancient Egyptian buildings used a wide variety of passive air-conditioning techniques. These became widespread from the Iberian Peninsula through North Africa, the Middle East, and Northern India. Split ac Passive techniques remained widespread until the 20th century, when they fell out of fashion, replaced by powered air conditioning. Using information from engineering studies of traditional buildings, passive techniques are being revived and modified for 21st-century architectural designs.     An array of air conditioner condenser units outside a commercial office building we allow the building’s indoor environment to remain relatively constant largely independent of changes in external weather conditions and internal heat loads. They also allow deep plan buildings to be created and have allowed people to live comfortably in hotter parts of the world .Split ac Heating Main article: Heat pump Some air conditioning systems have the option to reverse the refrigeration cycle and act as air source heat pump, therefore producing heating instead of cooling in the indoor environment. They are also commonly referred to as “reverse cycle air conditioners”. The heat pump is significantly more energy-efficient than electric resistance heating, because it moves energy from air or groundwater to the heated space, as well as the heat from purchased electrical energy. When the heat pump is in heating mode, the indoor evaporator coil switches roles and becomes the condenser coil, producing heat. The outdoor condenser unit also switches roles to serve as the evaporator and discharges cold air (colder than the ambient outdoor air). air conditioner Most air source heat pumps become less efficient in outdoor temperatures lower than 4°C or 40°F;this is partly because ice forms on the outdoor unit’s heat exchanger coil, which blocks air flow over the coil. To compensate for this, the heat pump system must temporarily switch back into the regular air conditioning mode to switch the outdoor evaporator coil back to being the condenser coil, so that it can heat up and defrost. Some heat pump systems will therefore have a form of electric resistance heating in the indoor air path that is activated only in this mode in order to compensate for the temporary indoor air cooling, which would otherwise be uncomfortable in the winter. air conditioner:- repair Newer models have improved cold-weather performance, with efficient heating capacity down to −14 °F (−26 °C). However there is always a chance that the humidity that condenses on the heat exchanger of the outdoor unit could freeze, even in models that have improved cold-weather performance, requiring a defrosting cycle to be performed. The icing problem becomes much more severe with lower outdoor temperatures, so heat pumps are sometimes installed in tandem with a more conventional form of heating, such as an electrical heater, a natural gas, heating oil, or wood-burning fireplace or central heating, which is used instead of or in addition to the heat pump during harsher winter temperatures. In this case, the heat pump is used efficiently during milder temperatures, and the system is switched to the conventional heat source when the outdoor temperature is lower. air conditioner-ledihatv.com

Based on the selected state, users can set the type of notification they want to receive and from which application. It is also possible to choose which pages and then apps to show on the Home based on the state. The state can change automatically based on where the user is or a time. Focus also controls the interactions with Contacts, so it is possible to decide which specific contacts can “disturb” the user. Some Lock Screen settings can be controlled based on the state: for example, the Dim Lock Screen feature, which darkens the lock screen from not showing notifications on that screen, can be automatically turned on or off based on the state. Focus is synchronized automatically across different iOS and macOS devices on the same iCloud account, as well as any paired watchOS devices. Notifications Notifications receive a new look with contact photos for all communication apps and larger app icons. When the notification arrives, the user can mute the corresponding app for one hour or all day. The Summary allows the user to group and postpone the notifications coming from the chosen apps, delivering them at a scheduled time in a single big notification called summary notification. Live Text Devices with an A12 chip or later support Live Text, which uses optical character recognition to recognize text in images, allowing copy-and-paste, look-up, and translation in Photos, Screenshot, Quick Look, Safari, and Live Preview with Camera. This feature uses artificial intelligence text recognition using the Neural Engine .iPhone 15 Smart stacks with suggested Widgets The Widgets in iOS 15 are now more dynamic: depending on the context, the system can add or remove widgets to existing stacks. For example, near the start of a certain event in the Calendar, the system can decide to add the Calendar Widget to an existing smart stack, if it is not already present, and then remove it at the end of the event. Iphone 15 Cross-App Drag and Drop Pictures and text can be dragged from one app and dropped in another. This feature was previously only available in iPadOS. Iphone 15 The various Home screens can be reordered, deleted, hidden, or limited using Focus mode .Iphone 15 Per-App Text Size From the Control Center, the text size can be set per app.  Iphone 15 Spotlight The global search function has been enhanced and it is also available on the lock screen by pulling the page down.

Holi

Happy Holi from Ledihatv.com Barsana, a town near Mathura in the Braj region of Uttar Pradesh, celebrates Lathmar Holi in the sprawling compound of the Radha Rani temple. Thousands gather to witness the Lath Mar Holi when women beat up men with sticks as those on the sidelines become hysterical, sing Holi songs and shout “Radhe Radhe” or “Sri Radhe Krishna”. The Holi songs of Braj Mandal are sung in pure Braj, the local language. Holi celebrated at Barsana is unique in the sense that here women chase men away with sticks. Males also sing provocative songs in a bid to invite the attention of women. Women then go on the offensive and use long staves called lathis to beat the men, who protect themselves with shields. Mathura, in the Braj region, is the birthplace of Krishna. In Vrindavan this day is celebrated with special puja and the traditional custom of worshipping Radha Krishna; here the festival lasts for sixteen days. All over the Braj region and neighbouring places like Hathras, Aligarh, and Agra, Holi is celebrated in more or less the same way as in Mathura, Vrindavan and Barsana. A traditional celebration includes Matki Phod, similar to Dahi Handi in Maharashtra and Gujarat during Krishna Janmashtami, both in the memory of god Krishna who is also called makhan chor (literally, butter thief). This is a historic tradition of the Braj region as well as the western region of India. Dahi Handi  An earthen pot filled with butter or other milk products is hung high by a rope. Groups of boys and men climb on each other’s shoulders to form pyramids to reach and break it, while girls and women sing songs and throw coloured water on the pyramid to distract them and make their job harder. This ritual sport continues in Hindu diaspora communities.[ Outside Braj, in the Kanpur area, Holi lasts seven days with colour. On the last day, a grand fair called Ganga Mela or the Holi Mela is celebrated. This Mela (fair) was started by freedom fighters who fought British rule in the First Indian War of Independence in 1857 under the leadership of Nana Saheb. The Mela is held at various ghats along the banks of the River Ganga in Kanpur, to celebrate the Hindus and Muslims who together resisted the British forces in the city in 1857. On the eve of Ganga Mela, all government offices, shops, and courts generally remain closed. The Ganga Mela marks the official end of “The Festival of Colours” or Holi in Kanpur. In Gorakhpur, the northeast district of Uttar Pradesh, the day of Holi starts with a special puja. This day, called “Holi Milan”, is considered to be the most colourful day of the year, promoting brotherhood among the people. People visit every house and sing Holi songs and express their gratitude by applying coloured powder (Abeer). Uttarakhand Main article: Kumaoni Holi Kumaoni Holi in Uttarakhand includes a musical affair. It takes different forms such as the Baithki Holi, the Khari Holi and the Mahila Holi. In Baithki Holi and Khari Holi, people sing songs with a touch of melody, fun, and spiritualism. These songs are essentially based on classical ragas. Baithki Holi (बैठकी होली), also known as Nirvan Ki Holi, begins from the premises of temples, where Holiyars (होल्यार) sing Holi songs and people gather to participate, along with playing classical music. The songs are sung in a particular sequence depending on the time of day; for instance, at noon the songs are based on Peelu, Bhimpalasi and Sarang ragas, while evening songs are based on the ragas such as Kalyan, Shyamkalyan and Yaman. The Khari Holi (खड़ी होली) is mostly celebrated in the rural areas of Kumaon. The songs of the Khari Holi are sung by the people, who, sporting traditional white churidar payajama and kurta, dance in groups to the tune of ethnic musical instruments such as the dhol and hurka. In the Kumaon region, the Holika pyre, known as Cheer (चीर), is ceremonially built in a ceremony known as Cheer Bandhan (चीर बंधन) fifteen days before Dulhendi. The Cheer is a bonfire with a green Paiya tree branch in the middle. The Cheer of every village and neighbourhood is rigorously guarded as rival mohallas try to playfully steal each other’s cheer. The colours used on Holi are derived from natural sources. Dulhendi, known as Charadi (छरड़ी) (from Chharad (छरड़)), is made from flower extracts, ash and water. Holi is celebrated with great gusto much in the same way all across North India. West Bengal   Happy Holi Celebration In West Bengal, Holi is known by the name of “Dol Jatra”, “Dol Purnima” or the “Swing Festival”. In Shantiniketan, West Bengal, Holi is known as “Basanta Utsav”. The festival is celebrated in a dignified manner by placing the icons of Radha and Krishna on a picturesquely decorated palanquin which is then taken round the main streets of the city or the village. On the Dol Purnima day in the early morning, students (mainly in Shantiniketan) dress up in saffron-coloured or pure white clothes and wear garlands of fragrant flowers. They sing and dance to the accompaniment of musical instruments, such as the ektara, dubri, and Veena. The devotees take turns to swing them while women dance around the swing and sing songs. During these activities, the people keep throwing coloured water and dry colours, abir, at them. Nepal Locals celebrating Holi in Kathmandu Durbar Square, Nepal Preparing for Holika Dahan, Kathamandu, Nepal. Women celebrating Holi in Kathmandu, Nepal. Tourists celebrating Holi in Pokhara, Nepal (2012) Locals celebrating Holi on the premise of Janaki Mandir, Janakpur, Nepal (2015) Holi, also known as Phagu Purnima, along with many other Hindu festivals, is celebrated in Nepal as a national festival. It is an important major Nepal-wide festival along with Dashain and Tihar (Dipawali). It is celebrated in the Nepali month of Falgun (Terai region celebrates on the same date as Indian Holi, while rest of the country celebrates it a day earlier), and signifies the legends of the Hindu god Krishna. They worship Saraswati shrine in Vajrayogini temples and celebrate the festival with their Hindu friends. happy Holi Traditional concerts are held in most cities in Nepal, including Kathmandu, Narayangarh, Pokhara, Itahari, Hetauda, and Dharan, and are broadcast on television with various celebrity guests. People walk through their neighbourhoods to celebrate Holi by exchanging colours and spraying coloured water on one another. A popular activity is the throwing of water balloons at one another, sometimes called lola (meaning water balloon).[103] Many people mix bhang (made from cannabis, milk and spices) in their drinks and food, as is also done during Shivaratri. It is believed that the combination of different colours at

mumbai

mumbai Mumbai ,(formerly called Bombay) is a densely populated city on India’s west coast. A financial center, it’s India’s largest city. On the Mumbai Harbour waterfront stands the iconic Gateway of India stone arch, built by the British Raj in 1924. Offshore, nearby Elephanta Island holds ancient cave temples dedicated to the Hindu god Shiva. The city’s also famous as the heart of the Bollywood film industry. ― by Google Early history     Kanheri Caves contain Buddhist sculptures and paintings dating from the 1st century CE to the 10th century CE. Mumbai is built on what was once an archipelago of seven islands: Isle of Bombay, Parel, Mazagaon, Mahim, Colaba, Worli, and Old Woman’s Island (also known as Little Colaba). It is not exactly known when these islands were first inhabited. Pleistocene sediments found along the coastal areas around Kandivali in northern Mumbai suggest that the islands were inhabited since the South Asian Stone Age. Perhaps at the beginning of the Common Era, or possibly earlier, they came to be occupied by the Koli fishing community. In the 3rd century BCE, the islands formed part of the Maurya Empire, during its expansion in the south, ruled by the Buddhist emperor Ashoka of Magadha.The Kanheri Caves in Borivali were excavated from basalt rock in the first century CE,and served as an important centre of Buddhism in Western India during ancient Times. The city then was known as Heptanesia (Ancient Greek: A Cluster of Seven Islands) to the Greek geographer Ptolemy in 150 CE. The Mahakali Caves in Andheri were cut out between the 1st century BCE and the 6th century CE.[68][69] Between the 2nd century BCE and 9th century CE, the islands came under the control of successive indigenous dynas: Satavahanas, Western Satraps, Abhira, Vakataka, Kalachuris, Konkan Mauryas, Chalukyas and Rashtrakutas, before being ruled by the Shilaharas from 810 to 1260.Some of the oldest edifices in the city built during this period are the Jogeshwari Caves (between 520 and 525), Elephanta Caves (between the sixth to seventh century), Walkeshwar Temple (10th century), and Banganga Tank (12th century). The Haji Ali Dargah was built in 1431, when Mumbai was under the rule of the Gujarat Sultanate. King Bhimdev founded his kingdom in the region in the late 13th century and established his capital in Mahikawati (present day Mahim).The Pathare Prabhus, among the earliest known settlers of the city, were brought to Mahikawati from Saurashtra in Gujarat around 1298 by Bhimdev. The Delhi Sultanate annexed the islands in 1347–48 and controlled it until 1407. During this time, the islands were administered by the Muslim Governors of Gujarat, who were appointed by the Delhi Sultanate. The islands were later governed by the independent Gujarat Sultanate, which was established in 1407. The Sultanate’s patronage led to the construction of many mosques, prominent being the Haji Ali Dargah in Worli, built in honour of the Muslim saint Haji Ali in 1431 From 1429 to 1431, the islands were a source of contention between the Gujarat Sultanate and the Bahmani Sultanate of Deccan. In 1493, Bahadur Khan Gilani of the Bahmani Sultanate attempted to conquer the islands but was defeated. by

Integrated circuit

Integrated circuit  Lediha electronics  “Silicon chip” redirects here. For the electronics magazine, see Silicon Chip. “Microchip” redirects here. For other uses, see Microchip (disambiguation).   INFORMATION BY  www. LEDIHATV.COM A microscope image of an integrated circuit  used to control LCDs. The pinouts are the black circles surrounding the integrated circuit. An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or “chip”) of semiconductor material, usually silicon. Large numbers of miniaturized transistors and other electronic components are integrated together on the chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count. The IC’s mass production capability, reliability, and building-block approach to integrated circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones and other home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs such as modern computer processors and microcontrollers. Integrated circuit [IC] Very-large-scale integration was made practical by technological advancements in semiconductor device fabrication. Since their origins in the 1960s, the size, speed, and capacity of chips have progressed enormously, driven by technical advances that fit more and more transistors on chips of the same size – a modern chip may have many billions of transistors in an area the size of a human fingernail. These advances, roughly following Moore’s law, make the computer chips of today possess millions of times the capacity and thousands of times the speed of the computer chips of the early 1970s. ICs have three main advantages over discrete circuits: size, cost and performance. The size and cost is low because the chips, with all their components, are printed as a unit by photolithography rather than being constructed one transistor at a time. Furthermore, packaged ICs use much less material than discrete circuits. Performance is high because the IC’s components switch quickly and consume comparatively little power because of their small size and proximity. The main disadvantage of ICs is the high initial cost of designing them and the enormous capital cost of factory construction. This high initial cost means ICs are only commercially viable when high production volumes are anticipated. First integrated circuits Main article: Invention of the integrated circuit See also: Planar process, p–n junction isolation, and Surface passivation Robert Noyce invented the first monolithic integrated circuit in 1959. The chip was made from silicon. A precursor idea to the IC was to create small ceramic substrates (so-called micromodules),each containing a single miniaturized component. Components could then be integrated and wired into a bidimensional or tridimensional compact grid. This idea, which seemed very promising in 1957, was proposed to the US Army by Jack Kilby and led to the short-lived Micromodule Program (similar to 1951’s Project Tinkertoy). However, as the project was gaining momentum, Kilby came up with a new, revolutionary design: the IC. Newly employed by Texas Instrumnts, Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working example of an integrated circuit on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as “a body of semiconductor material … wherein all the components of the electronic circuit are completely integrated”.The first customer for the new invention was the US Air Force.[15] Kilby won the 2000 Nobel Prize in physics for his part in the invention of the integrated circuit. Integrated circuit [IC] However, Kilby’s invention was not a true monolithic integrated circuit chip since it had external gold-wire connections, which would have made it difficult to mass-produce. Half a year after Kilby, Robert Noyce at Fairchild Semiconductor invented the first true monolithic IC chip. More practical than Kilby’s implementation, Noyce’s chip was made of silicon, whereas Kilby’s was made of germanium, and Noyce’s was fabricated using the planar process, developed in early 1959 by his colleague Jean Hoerni and included the critical on-chip aluminum interconnecting lines. Modern IC chips are based on Noyce’s monolithic IC, rather than Kilby’s. NASA’s Apollo Program was the largest single consumer of integrated circuits between 1961 and 1965.

Television (TV) is a telecommunication device used to transmit moving images. Televisions can display photos or videos in monochrome (black and white), or in color, and in either two or three dimensions. The term ‘television’ can refer to a television set or a television show. Televisions are commonly used for entertainment, advertising, news, and sports. Ledihatv By 2015, almost 85 percent of the world’s households owned a television set. The first televisions were cathode ray tube (CRT) devices. CRT televisions contain potentially lethal high-voltage capacitors, significant amounts of lead, and glass-walled vacuum tubes that can break violently. Beginning in the late 1990s, CRT displays were replaced with more compact, energy-efficient flat-panel televisions with liquid-crystal displays (LCDs, both fluorescent-backlit and LED), organic light-emitting diode (OLED) displays, and plasma displays. By the mid-2010s, most television manufacturers discontinued CRT,LED, DLP, plasma, and fluorescent-backlit LCD televisions. OLED displays began to gradually replace LED displays in the 2020s. Some television manufacturers have announced that they will increasingly produce smart televisions with integrated Internet and Web 2.0 functions.Ledihatv LEDIHA TV Standard television sets include multiple internal electronic circuits. These components include a tuner for receiving and decoding broadcast signals. A display device that does not include a tuner is commonly called a ‘television,’ but is correctly called a video monitor. If your television picture is cutting out, breaking up, or pixelating (looks like the picture is made up of many squares), the television may be receiving a weak signal. Ensure that all connections are tight by checking all of the connections from the wall to your cable box and from the cable box to the television. If you continue to experience pixelation problems, contact your cable or satellite provider.I m Lediha Electronics owner .
