ABSTRACT:
An equalizer arrangement comprises a fixed-characteristic equalizer which is supplemented by a variable-amplitude notch equalizer to enable proper equalization of signals transmitted via cables of arbitrarily mixed cable gauges. Automatic control of the notch amplitude is provided by detecting a predetermined signal level in the equalized signal, comparing this with its correct value, and controlling an up/down counter accordingly. The count of the counter determines a current flow through a diode which constitutes a variable resistance of the equalizer.
