The modulation -demodulation scheme proposed in this problem is similar to sinusoidal
Chapter 8, Problem 8.35(choose chapter or problem)
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 cos wet. The system is shown in Figure P8.35(a); the relation between cos wet and p(t) is shown in Figure P8.35(b). Let the input signal x(t) be a band-limited signal with maximum frequency WM
