Automatic gain control
In 1925, Harold Alden Wheeler developed an automatic volume control (AVC) system and later received U.S. Patent 1,866,687 for the invention. The patented system used a relay in the radio-frequency (RF) current path; detector plate current actuated the relay to regulate receiver gain. In a 1928 paper, Wheeler introduced a fully electronic version that eliminated the mechanical relay. In this design, the carrier signal was rectified, audio-frequency components were filtered out, and the resulting DC contro
