AUDIO_SWITCH

Published:2009/7/24 4:16:00 Author:Jessie | From:SeekIC

Switches audio signal on and off under control of flip-flop. With potentiometer across output, phase can be reversed. With two of these switches connected to same flip-flop, and each excited by different audio signal, potentiometer connected between B outputs will provide signal from wiper to ground that alternates from one audio signal to other as flip-flop changes state. Pot setting determines relative amplitudes of two signals. Can be used to generate a-f shift-keying signals.-F. Stevens, Audio On-Off, Phase-Reversing Switch, EEE,14:6, p 91-92.
