ABSTRACT:
A gain control circuit in which a switch is provided in series with a capacitor in a time constant circuit so that, under control of a controller, the switch is closed in its own signal reception and opened in an idle time other than the signal reception to perform gain control, whereby the capacitor can independently hold a signal reception level at the time of its own previous signal reception regardless of monitoring signal reception during the idle time.
