Abstract
In program material, the volume varies momentarily over a wide range. By reducing this range within reasonable limits, it is possible to increase the effective signal output of broadcast transmitters. Amplifier systems designed to reduce the volume range automatically have been in use for some time. The apparatus to be described here is an improvement in this type of device.
