1. a. A DSB-SC modulated signal is transmitted over a noisy channel with the given the power spectral density of the noise as following figure. The carrier signal and the message signal of the Modulated signal are c(t) = 0.5 cos (27100000t) and m(t) = .2 cos (2710000t). Determine the channel and the output signal-to-noise ratio of the signal. W(f) 10-6 f(KHz) -150 -50 50 150 b. An AM modulated signal is transmitted over a noisy channel with the given the power spectral density of the noise as figure above. The carrier signal and the message signal of the Modulated signal are c(t) = 0.5cos(27100000t) m(t) = 0.2 cos (2710000t). Determine the channel and the output signal-to-noise ratio of the signal at maximum amplitude sensitivity (ka,max).
