What is the purpose of diode in electronic circuit?
A diode presents a low resistance to current in one direction, and a high resistance to current in the opposite direction. This property is used to accomplish many different goals in various circuits. For example, it can be used to extract DC from an AC power supply, and it can be used to create new signals at frequency multiples of a pure signal.
What is a local oscillation?
A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)
What is the technology used by satellite television?
Satellite television suppliers use a number of technologies, most all of which in some way relate to the electronics industry. The video signal is sent up and down in a digital format, and it is digitally encrypted on the uplink and decrypted by the downlink receiver on your end. All of this could be grouped under "computer science" as it's all digital. The electronics portions use electronics technology to make the thing work. Let's look a bit closer. The signals on the uplink and downlink all operate on microwave frequencies. This is a "new and improved" version of radio signals (microwaves are like radio waves, only higher in frequency) that uses a dish of some sort as an antenna on the earthside ends. All kinds of electronics technology apply here. We also should mention the physics involved in putting the satellite up in space and parking it in orbit. Rockets and satellites operate because mechanical, aeronautical, electrical, electronic and chemical engineers make it happen. There are other engineering aspects included in this as well.
What is the difference between Traditional Media and New user driven media?
Traditional media is a media in which electronics equipment has not to be used by audience, in electronics media they require such instruments like radio, tv, computer etc to get the information.
How do you make bus port connectors in Logic Works?
Press Ctrl+B (or alternative go to "Schematic" --> " New Breakout") Enter the Bus name followed by the number of pins you want and press OK. example for name is D0..2 -> creates Bus D with signals D0, D1 , D2
It is a device that gathers the signals from that are connected to it and then regenerates a new copy of each signal?
The device you are describing is likely a signal repeater or signal booster. It receives incoming signals, amplifies them, and then retransmits a stronger copy of each signal to extend coverage or improve quality. This is commonly used in telecommunications to enhance signal strength in areas with weak reception.
A fairly new technology that uses radio signals to send and receive information is referred to as?
Answer is A. RFIDAnd NFCA fairly new technology that uses radio signals to send and receive information is referred to as. A. RFID. C. GUI. B. barcoding. D. MAR. 5.
What is radio taxi?
Radio taxi is a taxi that operates through radio signals. When a customer calls up the helpline number of the radio taxi, the operator communicates with chauffeur (driver) via radio signals to locate the nearest taxi. The taxi reaches the customer as required at the specific place and time. Radio taxis are one of the most popular means of transport in New Delhi. Abhishek.
Which one direction member did new zealand radio station zm interview?
Harry styles
Why doesn't the radio play one direction songs?
They do play songs of one Direction, but not all the time, because their quite a new band and not as famous as Justin Bieber or Robbie William's But they so sometimes play them when maybe your not listening to the radio.
Where was the dish televising the first lunar landing to the world situated?
The lunar landing was televised from signals sent to the Parkes Radio Telescope in New South Wales, Australia.
What were radios called in 1937?
By 1937, radio had long been known as "radio." But if you had been around in the early 1920s, radio was called a number of things-- wireless, wireless telephone, radiophone, and radio telephone. By the mid-1920s, however, the other words had fallen out of use, and radio was in fact only called "radio." What is interesting about 1937 is that FM was beginning to get into the news. In radio's first several decades, all stations were on AM. But in the late 1930s, inventor Edwin Howard Armstrong was demonstrating his new way of broadcasting-- which was generally referred to as "static-free radio"-- since AM signals tended to pick up all kinds of interference from the atmosphere, whereas FM signals did not.
What is digital radio?
Digital Radio is the coined name for the "New" generation of Radio broadcast; however, it should be noted that the technology has existed for years prior to its intial popularity with the inception of such well-known Satellite radio companies such as Sirius or XM.Note: Digital Radio does not have to originate from a satellite.Digital Radio has significant upgrades from the "Old" generation of Radio that used propogated terrestiral radio signals to trasmit a message called Analog Radio.These upgrades include primarily better sound quality.Unlike it's predecessor a more complicated computer is required to decode these digital signals and convert them into Audio; however, because of this Digital signals can hold more data than the old Analog Signals, allowing for more information such as Song Name date, and legtnh, to be processed simultaneously with the signal.Note: One drawback of digital radio is that if the signal becomes corrupted or blocked by too many barriers like thick concrete the signal will simply be cut out, unlike in analogue radio where you would still hear part of the broadcast with more static noise and distortion.
How do radio telescopes discover unknown bodies in space?
Radio telescopes can detect unknown bodies in space by picking up radio emissions from them. These emissions can reveal information about the composition, size, and distance of the object. By analyzing these signals, astronomers can identify new objects or phenomena in space that may have gone unnoticed through other means.
Hazard signals not working and turn signals not flashing in '99-00 Volvo S70's. How to fix?
The turn signals operate through the Hazard switch. The Hazard switch assembly is in the radio console inside the car and must be replaced. This unit is about $90 CDN and can be purchased from the dealership. I replaced mine by pulling out (Carefully!) the radio console (the owners manual will show you how to do this). After that, you: Push the old Hazard Switch out from the rear of the radio console. Unplug the wire at the end of the broken Hazard switch. Plug the wire into the new Hazard switch. Push the Hazard switch back into the radio console and slide the radio console back in place. It takes 2 minutes if you get someone to hold the radio unit while you change the switch. Good luck!
Can you use a radio receiver to transmit radio waves essentially turning it into a radio transmitter?
Some, but not all of them. Modern complex radio receivers have sections inside that generate new electrical signals, which are used to process the signal received by the antenna from a distant source. One part of the art of designing receivers ... and an FCC requirement ... is to prevent these locally-generated signals from escaping the receiver; if they got out, they would just become interference to legitimate communications. But if you know what you're doing and how to identify the right sections, there are points inside the receiver where you could connect an antenna and bring one of those locally-generated signals out of the receiver, and radiate it some distance to the outside world.
When was Radio New Zealand created?
Radio New Zealand was created in 1995.
