A male voice after modulation-transmission sounds like that of a female to the receiver. The problem is due to
Text Solution
Verified by ExpertsThe 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 received becomes more, which is possible with the poor bandwidth selection of amplifiers. It is so because bandwidth in amplitude modulation is equal to twice the frequency of modulation signal
