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 of the coherent detector y(t) would be
