B
The frequency of modulated wave varies as amplitude of modulating wave
C
The amplitude of modulated wave varies as amplitude of carrier wave
D
The frequency of modulated wave varies as frequency of modulating wave
Answer
The frequency of modulated wave varies as frequency of modulating wave
Explanation
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).
