ABSTRACT:
A compensation circuit for reducing intersymbol interference (ISI) products within an electrical data signal corresponding to a detected data signal received via a signal transmission medium provides for selective application of compensation to individual, discrete data signal components. According to one embodiment, one circuit branch processes the electrical data signal to substantially remove one distinct signal component representing an ISI product of some portion of the data symbol sequence. A second circuit branch approximately duplicates an ISI product of another portion of the data symbol sequence for removal by subtraction within a signal combiner from the compensated signal provided by the first circuit branch. A third circuit branch approximately duplicates an ISI product of still another portion of the data symbol sequence also for removal by subtraction within the signal combiner from the compensated signal provided by the first circuit branch.
