Question:

Can T.V Production can use a term F.M i.e frequency modulator. which is used in radio world?


Answers:

Yes.

TV uses two separate frequencies for their transmission, one carries the video signal, one carries the audio signal.

Believe it or not, it is possible to block or jam one signal or the other but let the remaining one go through, because they are on separate frequencies. This is why sometimes you may see an image but the sound is garbled, or the picture may be static but yet you can hear the sound perfectly clearly.

Ultimately, a TV is a radio that picks up two radio stations simultaneously. It just converts one signal in a signal pair into an image instead of outputting it as sound.
