A baseband signal m(t) that has a Gaussian (amplitude) distribution frequency modulates a transmitter. Assume that the modulation has a zero-mean value and a peak value of Vp = 4*(sigma). The FM signal is transmitted over an additive white Gaussian noise channel. Let Beta = 3 and B = 15KHz. Find (S/N)out/(S/N)baseband when: A. No deemphasis is used. B. 75-u sec deemphasis is used. Again I desperately need help with this problem too. I would appreciate any help.
