Consider a QAM demodulator whose local oscillator carrier is given by c(t) = eiod. The input QAM signal is oAM(t) = m(t) cos wet+ m2(t) sin ot. (a) Find the demodulated output signal for each of the two channels of the demodulator. (b) If the local carrier has a phase error of a and is given by c(t) = elot+a), obtain expressions for the demodu- lated output of each of the two channels.
