It is also called modulation of a digital signal. The baseband digital signal representing the digital data modulates the carrier to create a broadband analog signal.With Filter Discussion: 1. Explain the operation of the PCM encoder. 2. Discuss the effect of changing the number of bits in the output waveform. 3. Discuss the effect of changing the frequency of input analog signal on the reconstructed analog output signal. 4.
