In amplitude modulation, the amplitude of carrier wave is A c and that of the modulating signal is A m . In practice, the ratio of A m to A c is kept less than or equal to one, to avoid

Options

  1. ADistortion
  2. BAttenuation
  3. CFading
  4. DNoise

Correct answer

A. Distortion

Step-by-step solution

Modulation index, μ = A m A c < 1 is carried by the carrier wave, i.e. there is no original distortion.
