Abstract
A repeater for p.c.m. or digital transmission systems includes a secondary feedback control loop consisting of a low-pass filter and a peak detector to derive a control signal for a controllable impedance in the equaliser circuit. This control loop optimises the repeater performance for different cable types and characteristics with regard to the low frequency energy content of the eye diagram.
