AGC Time Const
AGC Time Const : Ant: (n.) Geophysics. A system to control the?gain, or the increase in the?amplitude?of an electrical?signal?from the original input to the amplified output, automatically. AGC?is commonly used in?seismic processing to improve visibility of late-arriving events in whichattenuation or wavefront divergence has caused amplitude decay. Alt. form: automatic gain control
