A modulating signal 2sin⁡(6.28×106)t is added to the carrier signal 4sin⁡(12.56×109)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.

Step-by-Step Verified Solution

WC=12.56×109\mathrm{W}_{\mathrm{C}}=12.56 \times 10^{9}

Wm=6.25×106

After amplitude modulation

Bandwidth frequency

=2Wm2π=2×6.282π×106=2MHz
