  • Abstract
    This paper presents a speakerphone IC dedicated to handsfree telephone set applications. The main charaterlstlc of this IC Is that it can adapt itself to the electrical and acoustical environment by changing Itself the gain of amplifiers and attenuators. This circuit can simulate closely a full-duplex handsfree system.
