What is the full form of DPCM?

  • Differential Pulse Code Modulation

What does DPCM mean?

DPCM is a technique of analog to digital signal conversion in which an analog signal is sampled and then the difference between the actual sample value and its predicted value is quantized and then encoded forming a digital value. Before we are discussing the differential PCM we have to know the demerits of PCM.
