Abstract

A simple, cost effective, volume control can be built for most electronic devices. Many consumer electronic products have adjustable controls for setting the vol- ume of a loudspeaker or transducer. These controls are usually expensive mechanical switches or potentiome- ters. However, switches and pots are notoriously unreli- able when used in harsh environments. Reliable electronic controls have been used in other applications, like VCR remotes, but the process of changing the volume setting can take several seconds.
