Step 1

For the synchronous normal AM demodulator shown in the figure. 

Electrical Engineering homework question answer, step 1, image 1

Given : gAM(t)=2[A+m(t)]cos ωct

If the two-sided channel PSD is η2( W/Hz).

1. We need to prove that SNR0=m(t)2¯ηfm

2. Then we need to prove that SNR0=m(t)2¯A2+m(t)2¯Siηfm
