An Economical RC Active Equalizer with Applications in Communications
B.B. Bhattacharyya, Soumik Das, M. N. S. Swamy · IRE Transactions on Communications Systems · 1977
A simple active equalizer network employing two operational amplifiers (OA's), five resistors, and a pair of capacitors is presented. The same network can be used for both amplitude and delay equalizations. Experimental results show that the circuit can be conveniently used for amplitude equalization in voice communications, and for delay equalization in private line data circuits.
