ABSTRACT:
An apparatus for predictive coding processing a digital signal comprises a selective predictive filter, responsive to an input signal for outputting a predictive residual signal, an adaptive predictive filter, responsive to the predictive residual signal, for outputting an optimal predictive residual signal, and a re-quantizing unit means for re-quantizing and outputting the optimal predictive residual signal. The positions of the selective and adaptive predictive filters may be interchanged and the processing apparatus may be either feed forward or feed back type.
