automatic gain control
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 automatic gain control
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. automatic gain control
automatic gain control (AGC), a feature of some hearing aids that reduces amplification at high-input intensity levels.au·to·mat·ic gain con·trol (AGC) (aw'tō-mat'ik gān kŏn-trōl') A feature of some hearing aids that reduces amplification at high-input intensity levels. See AGC
