Schematic of an AGC used in the analog telephone network; the feedback from output level to gain is effected via a Vactrol resistive opto-isolator.. Automatic gain control (AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input.

20 March 1880: National Bell Telephone merges with others to form the American Bell Telephone Company. 1 April 1880: world's first wireless telephone call on Bell and Tainter's photophone (distant precursor to fiber-optic communications) from the Franklin School in Washington, D.C. to the window of Bell's laboratory, 213 meters away.

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude (magnitude of the voltage or current) of a signal applied to its input ...
Robert Georges Nivelle [a] (15 October 1856 [1] – 22 March 1924 [2]) was a French artillery general officer who served in the Boxer Rebellion and the First World War.In May 1916, he succeeded Philippe Pétain as commander of the French Second Army in the Battle of Verdun, leading counter-offensives that rolled back the German forces in late 1916.

A maximum theoretical efficiency of 25% is obtainable using usual configurations, but 50% is the maximum for a transformer or inductively coupled configuration. [ 6 ] [ 7 ] In a power amplifier, this not only wastes power and limits operation with batteries, but increases operating costs and requires higher-rated output devices.
