Automatic gain control circuit |
摘要 |
An automatic gain control circuit includes a VCA, an AGC detector and an AGC time constant circuit which form an AGC loop. The AGC circuit further includes a level detector and a time constant designator. When the level detector detects an excess level of a signal derived from the VCA, the designator changes the time constant of the time constant circuit.
