Differen tial PCM

Introduction
In Chapter 2, we characterized speech and image signals waveforms. In this and in the two succeeding chapters, we describe
coding or predictive coding

as redundant

differential

systems where waveform redundancy is utilized in
to realize straightforward reductions in bit rate, for a

time- domain operations
specified quality of

Differential PCM (DPCM) coders, which are based on the notion of quantizing a prediction error signal, are important examples of predictive coding systems (Cutler, 1952) (Oliver, 1952) (Elias , 1955). DPCM deltamodulation systems with one-bit quantizers constitute an important subclass, digitization.

(Chapter 8).
The linear predictors

predictor coefficients (Section 6.4) lead to a class of
low-to-medium-complexity

coders which constitutes one example of the
