A DSBSC modulated signal is corrupted by an additive white Gaussian noise of power spectral density W/Hz. The message power spectral density is as shown in Figure and is uniformly distributed over the range 0 to 2π.
(a) Express the signal autocorrelation function in terms of the message autocorrelation function. Clearly state the necessary assumptions.
(b) Determine the signal power spectral density
(c) Find the power of the modulated signal and the noise power in the transmissions bandwidth.
(a)
(b)
(c)
Power of modulated signal = 150 W
Noise power in transmitted. BW = 1.2 W
(c)
Power of modulated signal = 1.2 W
Noise power in transmitted. BW = 150 W
