1) A message signal M(t) is wide sense stationary with the autocorrelation function RM(T) = 14sinc(1.5 x 1041). It is needed to transmit this message to a destination via a channel with 80 dB attenuation and additive white noise with the power spectral density Snf) = = 10-12 W/Hz . It is desired to achieve an SNR at the demodulator output of at least 30 dB. Find the required transmitter power, channel bandwidth and transmitter carrier amplitude for the following modulation schemes. a) DSB-SC-A.M. b) SSB-SC-A.M c) DSB-Full carrier-A.M. with a 70 % modulation. d) F.M. with a modulation index of 5 1) A message signal M(t) is wide sense stationary with the autocorrelation function RM(T) = 14sinc(1.5 x 1041).
