The modulation-demodulation scheme proposed in this problem is similar to sinusoidal amplitude modulation, except, that the demodulation is done with a square wave with the same zero-crossings as . The system is shown in Figure P8.35(a); the relation between and p(t) is shown in Figure P8.35(b). Let the input signal x(t) be a band-limited signal with maximum frequency , as shown in Figure P8.35(c)
