(a) Consider a message signal m(t) containing frequency components at 100, 200, and 400 Hz. This signal is applied to a SSB modulator together with a carrier at 100 kHz, with only the upper sideband retained. In the coherent detector used to recover m(t), the local oscillator supplies a sinusoidal wave of frequency 100.02 kHz. Determine the frequency components of the detector output.
(b) Repeat your analysis, assuming that only the lower sideband is transmitted.
