5-2 An AM transmitter is modulated with an audio testing signal given by $$m(t)=0.2\sin {?}_{1}t+$$ $$0.5\cos {?}_{2}t$$, where $$f_1=500\mathrm{Hz},f_2=500\sqrt{2}\mathrm{Hz}$$, and $$A_c=100$$. Assume that the AM signal is fed into a $$50??$$ load. (a) Sketch the AM waveform. (b) What is the modulation percentage? (c) Evaluate and sketch the spectrum of the AM waveform. 5-3 For the AM signal given in Prob. 5-2, (a) Evaluate the average power of the AM signal. (b) Evaluate the PEP of the AM signal.
