摘要：An equalizer with two parallel branches for precursor and postcursorcorrection, receiving periodically incoming binary pulse samples, generates for eachsample two purged symbols f, b at the outputs of these branches along with two decidedsymbols f and b, all of which are transmitted to a logic network checking whether or notthe two decided symbols are identical. In the event of a disparity, the network producesan estimated signal s, calculates the absolute differences d.sub. sf, d. sub.sb betweensignals s and f, b, supplements them with further signals d.sub.f, d.sub.b representing thecontributions of postcursors and precursors from one or more preceding and followingsamples, and compares resulting discriminatory signals D.sub.f and D.sub.b to determinewhich of the two decided symbols should be emitted as an output signal of the equalizer.
