How is radio and television signal transmitted?

Answer 1

A television signal contains a voice component which is an FM signal, and a video component which is an AM signal. The TV transmitter basically combines the voice and video information and puts it onto what is called a carrier wave for transmission into the air. Think of a car that is used to deliver a bag of groceries and a bag of hardware to a house, both accomplished at the same time. The carrier wave is what is sent into the air from the television tower. A TV receiver basically separates the voice and video info from the carrier, processes whats left, sends the video to the screen and the sound to a speaker. Now the circuits that accomplish that miracle are very complex, and my explanation is very simple. There are many good WEB sites and books on the subject. A understanding of basic electronics would go a long way in helping to grasp the principals. Cool right!

Answer 2

Light wave travels into the camera --> changes into image --> changes into electric

magnetic waves --> travels to broadcast --> sent to satellites --> sent to the wires

which connects to homes

Closed-circuit television (CCTV) are in use, the most common usage of the medium is for Broadcast Television, which was modeled on the existing radio broadcasting systems developed in the 1920s, and uses high-powered radio-frequency transmitters to broadcast the television signal to individual TV receivers.

Broadcast TV is typically disseminated via radio transmissions on designated channels in the 54-890 MHz frequency band.[1] Signals are now often transmitted with stereo and/or surround sound in many countries. Until the 2000s broadcast TV programs were generally transmitted as an analogue television signal, but in recent years public and commercial broadcasters have been progressively introducing digital television broadcasting technology.

A standard television set comprises multiple internal electronic circuits, including those for receiving and decoding broadcast signals. A visual display device which lacks a tuner is properly called a monitor, rather than a television. A television system may use different technical standards such as digital television (DTV) and high-definition television (HDTV). Television systems are also used for surveillance, industrial process control, and guiding of weapons, in places where direct observation is difficult or dangerous.

Amateur television (ham TV or ATV) is also used for experimentation, pleasure and public service events by amateur radio operators. Ham TV stations were on the air in many cities before commercial TV stations came on the air.

Answer 4

It is carried by a wire cable of the coaxial type, hence Cable, as opposed to broadcast television. In some instances the sound components of major TV live programs were carried in part on Coaxial (feeds) back in the sixties. these were live programs , not reruns or tapes. Nothing new under the Sun.
