Title: Automatic gain control circuit for video signal
Inventor: KONDOU KAZUO
IPC: H03G3/20
Filed: 1981-10-09
Abstract: PURPOSE:To attain the compatibility of the control characteristics at steady state and the transient response characteristics, by controlling a detection current circuit, a storage circuit and a switch circuit with two control signals and  increasing the discharge time constant of a peak value detection circuit. CONSTITUTION:When a video signal (a) is inputted at first, a large signal (b) is outputted from a gain variable amplifier 2. A peak value detection circuit 6 takes its peak value and a detection current (d) flows from a detection current detecting circuit 17, an output (f) of a storage circuit 20 holds the detection voltage and goes to low level. Next, when a control signal (e) is inputted, since the product between the signals (e) and (f) is a low level, a switch 21 is turned off. When a control signal (g) is inputted next, the signal (f) goes to a high level. Further, when the signal (e) is inputted, the product with the signal (f) goes to a high potential to turn on the circuit 21. Thus, a circuit 22 is connected to the circuit 6 and the detection voltage is lowered. Since the circuit 6 performs detection at each period of the signal (e), excellent transient response can be obtained even with a large time constant of the circuit 6. Further, the response at steady state is also excellent.
