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 amplifiers

C

poor selection of carrier frequency

D

loss of energy in transmission.

Text Solution

Verified by Experts

The correct Answer is:
B
Here, in this question, the frequency of modulated signal received becomes more, which is possible with the poor bandwidth selection of amplifiers.
This happens because bandwidth in amplitude modulation is equal to twice the frequency of modulating signal.
But, the frequency of male voice is less than that of a female.
