ABSTRACT:
An equalizer, consisting of a plurality of taps, each tap having a multiplier which is coupled to multiply a respective input sample by a respective coefficient, the taps being arranged in sequence so that the input sample to each of the taps, except to a first tap in the sequence, is delayed relative to a preceding tap in the sequence.The equalizer further includes an input selector, which is coupled to toggle the input sample to at least a selected tap among the plurality of taps, responsive to a state of the equalizer, so that the equalizer operates in a first state as a feed forward equalizer, and in a second state as a blind equalizer.
