Vedclass · Answer

(C) In standard television transmission systems,the audio signal is modulated using Frequency Modulation $(FM)$ to ensure high-quality sound and reduce noise interference. The video signal is modulated using Amplitude Modulation $(AM)$ (specifically Vestigial Sideband Modulation,which is a form of $AM$) to efficiently transmit the large bandwidth required for visual information. Therefore,the audio signal is frequency modulated and the video signal is amplitude modulated.

In $TV$ transmission,the audio signal is ........ modulated and the video signal is ........ modulated.
