49.
A device with input x(t) and y(t) is characterized by y(t) = x2(t). An FM signal with frequency deviation of 90 kHz and modulating signal bandwidth of 5 kHz is applied to this device. The bandwidth of the output signal is
Answer: Option
Explanation:
If we square the signal, bandwidth will becomes double.
B.W. for x(t) = 2(90 + 5) = 190 kHz
for x2(t) = 2 x 190 380 kHz.

Right answer is A.
Because modulating signal bandwidth doesn't change if pass through frequency doubler so required answer =2 (90x2+5) =370KHz.
