Question: An FM modulator operates with output xc ( t ) = 1 0 sin ( 2 0 0 t + ( t ) ) .

An FM modulator operates with output xc(t)=10sin(200t+(t)). The modulator operates with fd=2 Hz/V and the message signal m(t)=5sin(20t). The modulator is followed by a bandpass filter with a center frequency of 100 Hz and a bandwidth of 30 Hz.
