ADAPTIVE FILTER INCLUDING A DELAY CIRCUIT

18-12-1979 1 PHN 9389 "Adaptive filter including a delay circuit". In an adaptive filter having a delay circuit wherein amplitude control circuits are comprised in taps of that delay circuit which are controlled by means of an error signal which indicates the difference between an output signal of the filter and an output signal which has been brought in a desired waveform by a threshold circuit of the filter, a clamping control circuit is used which utilizes the integrated error signal as the control signal for matching the level of the output signal to a threshold level of the threshold circuit so that unwanted direct currents do not affect the amplitude control circuits. .
