An AM signal is given by (in volts): s(t) = 4 cos(2nfet) + 2 [cos (2nf?t) + cos (2nf?t)], where fc = 100kHz, f? = 93.5 kHz, f2 = 106.5 kHz. Let the modulator amplitude sensitivity be equal to 0.5 V-1. Answer the following questions. 7) What is the bandwidth of the modulated signal? 8) What is the amplitude of the modulating signal? 9) What is the modulation index? 10) What is the power in the side bands?
