A male voice after modulation-transmission sounds like that of a femal

1.	A male voice after modulation-transmission sounds like that of a female to the receiver. The problem is due toA. poor selection of modulation index (selected `0ltmlt1`)B. poor bandwidth selection of amplifiersC. poor selection of carrier frequencyD. loss of energy in transmission.
Answer» Correct Answer - 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.
