This video lecture is about the Differential Pulse Code Modulation (DPCM). What is redundant Information in PCM, has been explained with the help of waveform. Working Principle of Differential Pulse Code Modulation (DPCM) has been discussed with the help of diagram. Reconstruction of DPCM signal has also been explained in detail. At the end Comparison between PCM and DPCM have been done on various parameters.
