In TV, an electrical disturbance (noise) affects Correct Answer only the video signals

In TV transmission:

  • A video is Vestigial sideband modulated, which is a type of amplitude modulated waveform
  • The Video signals are thus encoded in amplitude variations of the carriers
  • The Audio signal is encoded in FM waveform
  • Thus, the audio signals are encoded as frequency variations of the carrier


Noise is the signal that affects amplitude majorly. Thus, the video signal is distorted from amplitude variations.
