Abstract

A signal for transmission is compared 12 with a prediction signal to produce a prediction error signal which is amplitude limited 8 and compressed 14 before transmission in analogue form. The limiter output is added 26 to the production signal and the resultant applied to a prediction function circuit 24 to generate the prediction signal. At the receiver, the analogue signal is expanded 20 and applied to a similar adder 26 and prediction function circuit 24. The system is useful with MAC type television signals and enables a reduction of noise effects on fm transmission. <IMAGE>
