In frequency modulation

  • A
    the amplitude of modulated wave varies as frequency of carrier wave
  • Correct answer
    B
    the frequency of modulated wave varies as amplitude of modulating wave
  • C
    the amplitude of modulated wave varies as frequency of carrier wave
  • D
    the frequency of modulated wave varies as frequency of modulating wave

Solution

The process of changing the frequency of a carrier wave (modulated wave) in accordance with the audio frequency signal (modulating wave) is known as frequency modulation (FM).

Hence, the correct answer is option: 'B'.
