1. A DSB-SC modulated signal is transmitted over a noisy channel with the power spectral density of the noise being as shown in the figure below. The message bandwidth is 4 kHz and the carrier frequency is 200 kHz. Assuming that the average power of the modulated wave is 10 watts, determine the output signal-to-noise ratio of the receiver. SN (f) W/Hz 10-6 -400 400 f(KHz)
