Consider a message signal m(t) containing frequency components at 100, 200, and 400 hz. this signal is applied to an 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 sine wave of frequency 100.02 khz. determine the frequency components of the detector output. repeat your analysis, assuming that only the lower sideband is transmitted.
