Since the difference between adjacent time samples for speech is small, coding techniques have evolved based on transmitting sample-to-sample differences rather than actual sample values. Successive differences are in fact a special case of a class of non-instantaneous converters called N-tap linear predictive coders. These coders, sometimes called predictor-corrector coders, predict the next input sample value based on the previous input sample values. This structure is shown in Figure 13.20. In this type of converter, the transmitter and the receiver have the same prediction model, which is derived from the signal's correlation characteristics. The encoder forms the prediction error (or the residue) as the difference between the next measured sample value and the predicted sample value. The equation for the prediction loop is
