ABSTRACT:
In a device for equalizing multiphase and/or multiamplitude modulated data signals, which device includes a decider connected to receive a demodulated input signal and to produce a demodulated output signal, an equalizer, and a difference forming member connected to produce an output signal representative of the difference between the demodulated decider output and input signals, the difference forming member output signal being supplied to the equalizer as a control value for adaptively setting the equalizer coefficients, a multiplier is connected between the decider and the equalizer for multiplying the signal supplied thereto by a positive scalar value.
