Onsider a message signalm(t) containing frequency components at 100, 200,and 400 Hz. (a) This signal is applied to a USB modulator together with a carrier at 100 kHz. The received signal is identical to the transmitted signal. However, in the demodulator used torecoverm(t), the local oscillator supplies a sinusoidal wave of frequency 100.02 kHz instead of 100kHz. Determine the frequency components of the detector output. (b) Next, consider the output frequency components when LSB is applied.
