Derive an expression for the post-detection signal-to-noise ratio of the coherent receiver of Fig. 9.6, assuming that the modulated signal is produced by sinusoidal modulating wave

 

Perform your calculation for the following two receiver types:

(a) Coherent DSB-SC receiver

(b) Coherent SSB receiver

Assume the message bandwidth is fm. Evaluate these expressions for a received signal strength of 100 picowatts, noise spectral density of 10-15 watts per hertz, and fm of 3 kHz.
