JEE Main 29 July 2022, Shift 2, Physics Q55

Question 55 of 90 in this shift, Physics question 25 of 30, Section B.

A modulating signal 2sin⁡(6.28×106)t2\sin(6.28\times10^{6})t is added to the carrier signal 4sin⁡(12.56×109)t4\sin(12.56\times10^{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.
