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
