Detailed explanation-1: -TV broadcasting uses frequency modulation for the audio part and amplitude modulation for the video part as different modulations provide different advantages. Was this answer helpful?

Detailed explanation-2: -Frequency modulation is required for television broadcast.

Detailed explanation-3: -Detailed Solution. Amplitude Modulation (AM) is preferred for picture transmission in TV because of the following reasons: The distortion which arises due to interference between multiple signals is more in FM than AM because the frequency of the FM signal continuously changes.

Detailed explanation-4: -Television sound: The video information in a television broadcast is transmitted using AM, while FM is used for sound transmission due to low interference. Satellite TV: Some satellites use FM to broadcast video signals on the receiver’s station.
