ML1490 General Description

OF SPEECH COMPRESSOR The amplifier drives the base of a PNP transistor operating common

*emitter with a voltage gain of approximately 20. The control R1 varies the quiescent Q point of this transistor so that varying amounts of signal exceed the level Vr. Diode D1 rectifies the positive peaks.
