Consider a message signal m(t) with bandwidth W = 5.86 kHz. This
signal is applied to a product modulator, together with a carrier
wave c t = cos(210000πt) producing the DSB-SC modulated
wave s(t). This modulated wave is next applied to a coherent
detector producing an output signal y(t). The coherent detector
consists of a product modulator that multiplies s(t) by c
r = 2cos(222000πt) and a low pass filter which has a cut
off frequency 21 kHz. The output...
