Use Matlab to plot the waveform x(t)=Acos(2Πfct)sin(2Πf1t) for A=3, fc=l6, and f1=2. Plot for two full cycles, and specify the period of x. What sampling rate did you choose? Describe how you can compute the average power of this waveform?
(We assume it is a voltage or current waveform, and use a normalized impedance of R=1 ohm.)
