lowpass filter G(ω) with cutoff frequency W. In practice, the demodulator shown above should be preceded by a receivebandpass filter that passes s(t) and eliminates out-of-band noise. Frequency Domain Analysis of Operation Remember that b(t) = s(t)2cosωct. So B(ω) = S(ω +ωc)+S(ω −ωc) This translates the sidebands around ±ωc down
