Abstract
A waveform equalizer includes: a data signal input terminal for receiving an input data signal which is the object of waveform equalization; a plurality of S/H circuits each connected to the data signal input terminal; a sampling control circuit for repeatedly bringing the plurality of S/H circuits, one by one, to a sampling operation state; a selection circuit for selecting outputs of a predetermined number of S/H circuits which are in a hold operation state, respectively, from among the plurality of S/H circuits; a weighting circuit for weighting the outputs of the predetermined number of S/H circuits selected by the selection circuit; and an addition circuit for effecting an addition of outputs of the weighting circuit, thereby obtaining a waveform-equalized data signal from an output end of the addition circuit. By the constitution, it is possible to carry out a waveform equalization with high precision, and to realize a high speed of operation and a reduction in the scale of circuit.
