In frequency modulation
A
The amplitude of modulated wave varies as frequency of carrier wave
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 chaining the frequency of a carrier wave (modulated wave) in accordance with the audio frequency signal (modulating wave) is known as frequency modulation (FM)
