<p>In transmitting a residual signal determined by the difference between an input signal and a predictive signal, a comparative signal based on the input signal is applied to a plurality of predictors having different respective predictive functions or coefficients, the resulting respective predictive output signals from the predictors are compared with the comparative signal to provide respective difference signals, and the predictor corresponding to the smallest of the difference signals with a predetermined time delay, for example, the next preceding sampling of the input signal, is employed as the source of the predictive signal to be subtracted from the input signal for determined the transmitted residual signal.</p> |
