Q13) Consider an AM-DSB-C system with Am cos(21tfmt) as the message signal. The transmitted AM signal is given by: s(t) = 10 cos(500nt) + 40 cos(2000nt) + 10 cos(3500nt). (a) Determine fm [2 marks] (b) Determine the carrier frequency. [2 marks] (c) Determine the modulation index. [2 marks] (d) Is demodulation using an envelope detector possible? Motivate. [2 marks]
