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.
Prob. 5–2
An AM transmitter is modulated with an audio testing signal given by m(t) = 0.2 sin v1t + 0.5 cos ω2t, where Assume that the AM signal is fed into a 50-Ω load.
(a) Sketch the AM waveform.
(b) What is the modulation percentage?
(c) Evaluate and sketch the spectrum of the AM waveform.
