Abstract
A closed feedback loop controls the adaptive equalization of an incoming data signal received via a cable. Detected signal information about the positive and negative peaks of the incoming data signal during different windows in time is processed to generate a set of adaptive equalization control signals which identify differences, if any, between the positive and negative peaks of the present data signal and those which are desired. These equalization control signals control an input signal equalization circuit which adaptively adjusts the waveshape of the present data signal to bring it into conformance with the desired waveshape.
