The device comprises a waveform equaliser having a transversal filter connected to receive an input signal having a linear distortion, and having controllable tap gains. A tap gain correcting device is provided for successively correcting the tap gains of the transversal filter to take from the transversal filter and output signal from which the linear distortion is removed. The tap gain corrector means is arranged to add a small leak to the correction control of tap gains. The magnitude of this leak is increased or decreased depending upon the sum of absolute values of the differences between the tap gains and their predetermined values.
