automatic gain control

n
(Electronics) control of a radio receiver in which the gain varies inversely with the magnitude of the input, thus maintaining the output at an approximately constant level. Abbreviation: AGC

The HPU 42000 series Raman amplifiers, which feature built-in automatic gain control (AGC) function, offer ease of system implementation and excellent noise characteristics, which, in combination with erbium-doped fiber amplifiers (EDFAs), improves optical signal to noise ratio (OSNR) as well as compensates for optical loss resulting from optical transmission lines and optical components.
Hittite Microwave Corporation has introduced the first product in the new Automatic Gain Control product line.
Based on a Multi-Loop dynamic range control principle, Level Magic can simultaneously handle slow changes (automatic gain control), fast changes (transient processing) and 'look-ahead' peak limiting, thus offering level management with exceptionally high audio quality and without colouration, pumping, breathing, distortion or modulation effects.
Automatic gain control compensates for dirty optics, rain, and fog.
Chapters include discussions on superheterodyne receivers, dynamic range, mixers, frequency synthesizers, automatic gain control and beat frequency oscillators and additional sections cover advanced topics like digital signal processing and software radio as well as electronic warfare receivers.
Features include acoustic echo cancellation, automatic gain control, speech enhancement, improved call setup speed, increased battery life, local and network provisioning, and improved dual-mode management.
This paper proposes a histogram equalization technique with AGC (Automatic Gain Control) to extend the image enhancement range.
We managed to reduce power consumption and chip surface area (two important parameters in designing integrated circuits) simultaneously with power loss by applying new circuit methods in automatic gain control systems.
There's automatic gain control and noise suppression, which eliminates the need to play with any settings.<p>Our Comcast network speed is pretty bad (typically about 384Kbps to 512Kbps), so we didn't have to do anything special to test Lost Packet Recovery.
The amplifier settles in less than 5 ns from a gain change, producing low glitch noise and supporting very fast and accurate AGC (automatic gain control) performance.
Automatic Gain Control (AGC) allows the receiver to compensate for varying site conditions.
