Abstract
An equalizer for use in a receiving system of a code transmission system has a plurality of series-connected delay elements, a plurality of coefficient units for weighting tap output signals extracted in parallel from the delay elements, an adder for adding output signals from the coefficient units, and a tap coefficient setting circuit for adjusting the weighting of the coefficient units. The tap coefficient setting circuit has a multiplier for multiplying a differential signal, the differential signal representing a difference between an output signal from the equalizer and a predetermined reference signal, and the tap output signals, a variation detecting circuit for being supplied with an output signal from the multiplier and detecting a variation of tap coefficients, and an accumulating circuit for outputting established tap coefficients based on an output signal from the variation detecting circuit.
