Title: Adjustable digital filter for high speed digital transmission

Abstract: An adjustable digital filter combines the functions of a conventional digital filter and a conventional equalizer and permits elimination of the additional delay stages conventionally required for the equalizer. Reduced complexity and expense are attained, along with improved performance, since the elimination of "delay-and-add" stages required by prior art equalizers permits detection and correction of error with less delay than the prior art. Hence, improved performance is realized along with reduced cost.
