Abstract
A decision feedback encoder comprising an analog-to-digital converter for converting an input signal into digital signals representing decision levels, digital processing circuits responsive to signals from the converter for providing a succession of symbol values and a set of coefficients, digital-to-analog converters for converting the coefficients into corresponding analog values and analog circuits for forming a sum of the products of each of the symbol values and a respective one of said analog values to provide a feedback signal for the reduction of inter-symbol interference in the input signal.
