Summary

Description

Basic +20dB, automatic gain control cell - as used in 1970s telephone networks. Adapted from A. V. Yushin (1998, in Russian). Оптоэлектронные приборы и их зарубежные аналоги (Optoelectronnye pribory i ih zarubezhnye analogi). Radiosoft Moscow. Volume 1. ISBN 5855540000 Invalid ISBN. p. 323.

Note that capacitor values are chosen to narrow passband to telephony standard; hi-fi passband would need at least 100nF values for both C1, C2.
