ABSTRACT:
Minimal realization of an optimum amplitude and phase equalizer is disclosed. A first amplifier circuit including first respective passive filter elements provides both high and low frequency amplitude equalization. A second amplifier circuit including second respective passive filter elements provides first, second or higher order phase equalization, respectively, with gain. The equalizer operates between voltage sources and virtual ground to minimize noise picked up from parasitic capacities and external sources.
