WebNov 22, 2024 · Differential Pulse Code Modulation differs from Pulse Code Modulation as a results of it quantizes the excellence of the actual sample and expected value. that’s the reason it’s cited as differential Pulse Code Modulation(DPCM). ... feedback exists in both the transmitter and receiver. 2. signal-to-noise ratio: DM has a poor signal-to-noise ... WebThe DPCM receiver has the job of converting the received code blocks back into sample. FIG. 4 illustrates such a DPCM receiver. The data blocks are supplied to a decoder 31 via an input 30. The decoder 31 contains an elastic memory and a decoder arrangement, so that the DPCM values Δs or samples s are output at the outputs of the decoder.
