An am transmitter is modulated with an audio testing signal given by m(t) = 0.2 sin v1t + 0.5 cos v2t, where f1 = 500 hz, f2 = 500 12 hz, and ac = 100. 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.
