DPCM - Definition by AcronymFinder

Differential pulse-code modulation (DPCM) is a signal encoder that uses the baseline of pulse-code modulation (PCM) but adds some functionalities based on the prediction of the samples of the signal. The input can be an analog signal or a digital signal. If the input is a continuous-time analog signal, it needs to … See more The encoder performs the function of differentiation; a quantizer precedes the differencing of adjacent quantized samples; the decoder is an accumulator, which if correctly initialized exactly recovers the … See more The incorporation of the decoder inside the encoder allows quantization of the differences, including nonlinear quantization, in the … See more • Adaptive differential pulse-code modulation • Delta modulation, a special case of DPCM where the differences eQ[n] are represented with 1 bit as ±Δ • Pulse modulation methods See more WebMar 7, 2012 · 2 This principle is known as posteriori decision making. 3 In case of unequal transmission probabilities, the decision threshold moves away from the symbols with higher transmission probability . difference between axis and atlas vertebraeWebDifferential Pulse Code Modulation, DPCM DPCM is exactly the same as predictive coding except that it incorporates a quantizer step.
