A tap-weight controller of a matched filter includes a tapped delay line having a series of delay elements for receiving an incoming digital signal to produce successively delayed signals at successive taps of the delay line so that the signal at the center tap coincides with the output of a decision feedback equalizer (DFE). Correlation circuits are provided corresponding respectively to tap-weight multipliers of a transversal filter and to the taps of the delay line of the tap-weight controller. In each correlation circuit, correlation is detected between the output of the DFE and a signal from the corresponding tap of the delay line, and a signal indicating the detected correlation is integrated over a prescribed interval. An adder has a first input for receiving the detected correlation signal and a second input for receiving the integrated signal or a tap-weight control signal to produce a summed signal. The correlation signal is delayed for an interval equal to the prescribed interval and subtracted from the summed signal to produce an output which is applied to the adder as the tap weight control signal as well as to the corresponding tap-weight multiplier. The integrated signal is initially applied to the second input of the adder, and thereafter, the tap- weight control signal is applied to the adder to update the control signal at symbol intervals.
