Question:
A DSB-SC modulated signal is demodulated by applying it to a coherent detector. Evaluate the effect of a frequency error delta f in the local carrier frequency of the detector, measured with respect to the carrier frequency of the incoming DSB-SC signal. For the case of a sinusoidal modulating wave, show that because of this frequency error, the demodulated signal exhibits beats at the error frequency. Illustrate your answer with a sketch of this demodulated signal
