Voice-activated AGC for teleconferencing
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002In a group teleconference, sound pressure levels at the microphone vary due to variations in speaking distances and loudness. The conventional automatic gain control (AGC) appropriately adjusts the microphone gain so as to achieve a constant level. However, due to the lack of discrimination between speech and nonspeech sounds, nonspeech sounds can ...

… the output (BM displacement or velocity) varies much less than the stapes input displacement or velocity, for frequencies near the best frequency. The significance of this important finding will become clearer as we proceed, but, in my opinion, it is a precursor to an automatic gain control system which seems to be built into the cochlear filters. —“

IEEE Transactions on Broadcast and Television Receivers, 1971
The change of the IF response with gain (usually called the "pole shifting IF") has been a well-accepted practice in the design of the tube television receivers, both color and black and white. The tube parameter employed most often was the change of the input impedance with gm in a pentode tube.

This chapter provides the reader with an introduction to the theory of feed forward (FF) and feedback automatic gain control (AGC) systems, followed by design examples, noise analysis, and design approaches for practical FTTx an analog receivers. This is a key chapter and has a major importance when designing any amplitude control system for hybrid ...

AGC in Transistor Broadcast Receivers
IRE Transactions on Broadcast and Television Receivers, 1962This paper is an attempt to derive just what kind of an age characteristic can be expected of a particular design and why this is obtained. To do this the paper examines the processes used for agc in transistor broadcast receivers, their limitations, their application to typical receivers, the results obtained and the various circuits that can be used ...

Airborne teletypewriter AN/AGC-1
Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1958The transmission of information by teletypewriter means has proved itself, as shown by the number of civilian and military networks now in operation. The advantage of this method over voice lies in its reduced bandwidth and the production of printed copy.
