automatic gain control

[¦ȯd·ə¦mad·ik ′gān kən‚trōl]
(electronics)
A control circuit that automatically changes the gain (amplification) of a receiver or other piece of equipment so that the desired output signal remains essentially constant despite variations in input signal strength. Abbreviated AGC.

Digital Automatic Gain Control (AGC) technology that allows for "Smart" amplification, optimizing the signal for lowest noise and highest throughput.
The Sonaptic Sound Engine also supports both MP3 and SBC decoding for the most common music formats; whilst the automatic gain control ensures that high quality audio is maintained even in conditions of varying input levels.
Other features include line-lock, automatic gain control, backlight compensation, auto white balance, flickerless mode, a signal-to-noise ratio of 51 dB, and 480 lines of resolution.
Integrated on the transceivers are 12-bit, 160 mega-samples-per-second (MSPS) ADCs and DACs, along with smart system features such as self-calibration, automatic gain control, transmit power control, support for automatic frequency control, and auxiliary ADCs and DACs for system monitoring.
11 a/b/g transceivers, sigma-delta ADCs, DTV tuner automatic gain control with bandgap and bias, high-speed I/O, and post-layout multi-GHz PLLs.
The system features a 6 MHz per channel bandwidth, optical automatic gain control, and various diagnostic indicators.
SoftRISC will also provide Symbol with solutions critical for deploying enhanced VoWiFi, including ITU compliant Speech Codec along with integrated Acoustic Echo Canceller and Automatic Gain Control.
The Si4700 integrates selectivity filtering, automatic gain control, a frequency synthesizer and audio processing.
The solution bundle integrates optimized codecs, adaptive jitter buffer and PLC, voice enhancement components (Full-duplex Acoustic Echo Cancellation, Automatic Gain Control, Noise Suppression); supports built-in or 3rd party SIP stack, provides network support (RTP/RTCP) and call control API, integrates network and voice processing subsystems ensuring the lowest impact on CPU performance.
Five types of broadband circuits are discussed in detail: - Transimpedance amplifiers - Limiting amplifiers - Automatic gain control (AGC) amplifiers - Lasers drivers - Modulator drivers.
