Abstract
PURPOSE: To secure such constitution that can be applied to both a forward-phase and backward-phase feedback amplifiers and at the same time ensure an optional setting of the muting time.
CONSTITUTION: The switch 30 is opened after discharging the capacitor 25 during a make of the power supply voltage 5 or with the switch 30 closed, and then the charging is started. Thus the potential V2 of the terminal 24 increases higher than the potential V1 of the terminal 20 since the capacitor 25 receives a constant current charging with the constant current source 26. However, the switch 13 is turned off since the transistors 15 and 16 are turned on and off respectively. Thus the amplifier 4 starts its normal amplifying action.
