AM, PM, and FM Signals in Noise: Audio and SNR Simulations
http://homepages.wmich.edu/~bazuinb/ECE4600/Project.pdf
AM, PM, and FM Signals in Noise: Audio and SNR Simulations Project Due: 6 December, 2021 An understanding of the performance of communications systems in the presence of additive white Gaussian noise (AWGN) is necessary if a person is interested in a carrier in communications. This project is intended to expand upon the theoretical material

with the simulation result for audio SNR between 0 dB and 20 dB. For audio SNR < 0 dB, there is a 1–3 dB difference between the simulation and experimental result. For audio SNR >20 dB, the difference between the simulation and experimental results increases and becomes asymptotically large at audio SNR of 25 dB. This is an expected behavior.

This SNR improvement offered by the FM system counteracts the strong decrease in ampli-tude of e.g. a speech level with increasing distance from the speaker. There is an energy loss of roughly 6

T = 2W (for SSB, the SNR performance is again identical, but the transmission bandwidth is only B T = W). FM: The SNR performance is 15.7 dB better than a baseband system, and the transmission bandwidth is B T = 2(β+ 1)W = 12W (with pre- and de-emphasis the SNR performance is increased by about 13 dB with the same transmission bandwidth).

Performance of Amplitude Modulation [1, 2] We have seen that the a normal amplitude-modulated signal is given by sc(t)= [A + m(t)] cos 2πfct (29.1) = A[1 + 1 A m(t)] cos 2πfct (29.2) where A is a constant, m(t) is the modulating signal, and fc is the carrier frequency.
