A male voice after modulation-transmission sounds like that of a female to the receiver. The problem is due to

A

poor selection of modulation index (selected `0ltmlt1`)

B

poor bandwidth selection of amplitudes

C

poor selection of carrier frequency

D

loss of energy in transmission

Text Solution

Verified by Experts

The correct Answer is:
B
The frequency of male voice is less than that of a female voice in the given problem, the frequency of modulated signal recived becomes more, which is it is so because bandwidth in amplitude modulation is equal to twice the frequency of modulation signal.
