Question
Assume that an AM system operates with an index of 0.8 and that the message signal ism(t) = 4cos(2(750)t). Compute the SNR in terms of NW (consider only two digits after the decimal point) Answer: Consider an AM system that operates with an index of 0.76 and consider a message signal m(t) = used, answer the following questions: 100cos(200nt). Assuming that coherent demodulation is 1- Determine the efficiency. Answer 2- Determine the output SNR in terms of (NW) Pr (N,W) Answer 3- Determine the detection gain. Answer 0.224 0.76 1.52 100 2 0.448 1 3.04 200 TOSHIBA
