17 ABSTRACT: Differential pulse code modulation transmission system in which the transmitter and the receiver each comprises a predication circuit for generating a predication signal from the transmitted DPCM-signal. This predication circuit is in the form of two or more prediction channels 710(i) each consisting of a non-linear network 711(i) followed by a leaky integrator circuit 700(i). The in- puts of these prediction channels are connected to a com- mon input 701 and the output of each prediction channel is connected to an input of a summing device 712, which produces the desired prediction signal.
