We see from your search that you're looking for information on the term "AGC (automatic gain control)",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Gain control keeps TV volume steady from
SRS Labs, which we summarised at the time by saying "Cirrus Logic is the first chipmaker to feature SRS Volume IQ, which will be made available through its CS485xx family of audio DSPs for TV, home theatre and automotive entertainment markets".
Earlier in the week,
we featured the news release Single-stage TV tuner cuts consumption from
Maxim Integrated Products: "Highly integrated single-conversion television tuner for ATSC and NTSC applications covers the full 54 to 860MHz frequency range".
In January 2008, we covered the news from Acrosser
concerning its Acrosser's Wager series
- take a look at Gaming platforms suit multiple countries
which says: "The AGB model AR-B5600 gaming board uses Intel's GME965 mobile chipset, which supports dual and single-core mobile processors".
Take a look also at the news release from Analog Devices, Transceivers integrate full WiMAX feature set,
as well as Chipset boosts basestation receiver bandwidth from Analog Devices,
and Driver speeds fibre-optic comms from Link Microtek.
