What is the function of AGC optical communication products
In 1925, 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 (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.
