Abstract

PURPOSE:To reduce the delay of a device in following up sudden variations of an input signal by switching time constants by a gain control circuit. CONSTITUTION:On the basis of a time-constant switching signal inputted to a switching input terminal 4, a time-constant switching device 5 selects a time- constant circuit to switch time constants. To the switching input terminal 4, a signal is applied at this time to switch the time constant for channel selection and normal reception, for example. The time constant of a time-constant circuit 8 is set less than that of a time-constant circuit 6. In channel selection wherein an input signal varies suddenly and frequently, a control circuit 7 responds with the small time constant of the time-constant circuit 8. Therefore, the following-up delay of control is reduced and malfunction is prevented. In normal reception, on the other hand, the device responds with the time constant of the time-constant circuit 6.
