A modulating signal 2sin(6.28 x 10 6 )t is added to the carrier signal 4sin (12.56 x 10 9 )t for amplitude modulation. The combined signal is passed through a non-linear square law device. The output is then passed through a band pass filter. The bandwidth of the output signal of band pass filter will be ___ MHz.

Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(2)
Frequencies present in output of square law device
After passing through band bass filte.
Band width = 2f m
= 2 MHz
