Distributive encoder for encoding error signals which represent signal

Abstract

A distributive encoder for receiving and processing digital error signals representing variations in peak values of an equalized incoming digital data signal and in accordance therewith encoding error signals which represent signal peak errors in data signals for purposes of identifying erroneous signal baseline, peak and equalization conditions. The digital error signals represent variations in peak values of an equalized incoming digital data signal which includes a data signal baseline intermediate to its positive and negative peaks. Two sets of the digital error signals identify when present positive and negative levels transcend prior positive and negative levels, respectively, of the equalized incoming digital data signal. Using various subsets of these digital error signals, the distributive encoder generates encoded error signals which identify erroneous signal baseline, peak and equalization conditions. Using various ones of these encoded error signals, a baseline control circuit can generate a baseline control signal for use in controlling a correction of the equalized incoming digital data signal baseline, a peak control circuit can generate a peak control signal for use in controlling compensation for the positive and negative peaks of the equalized incoming digital data signal, and an equalization control circuit can generate a set of equalization control signals for use in controlling the equalization of the incoming digital data signal.
