单词 | automatic gain control |
释义 | automatic gain control in British Englishnoun 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: AGCautomatic gain control in Electrical Engineering (ɔtəmætɪk geɪn kəntroʊl) or AGC noun (Electrical engineering: Computing and control) Automatic gain control is a circuit that modulates an amplifier's gain, in response to the relative strength of the input signal, in order to maintain the output power. The effect of the automatic gain control is to reduce the gain and the signal level provided to a successive output bufferstage in order to improve the linearity of the overall amplifier chain. Some telephone recording devices incorporate automatic gain control to produce acceptable-quality recordings. Automatic gain control is a circuit that modulates an amplifier's gain, in response to the relative strengthof the input signal, in order to maintain the output power. |
