IPC: H03G3/20
Filed: 1982-08-27
Abstract: PURPOSE:To quicken the response of an AGC device, by providing additionally a means possible for changing a smoothing time constant to a signal detector. CONSTITUTION:When no AM input signal is applied to an input terminal 1 of a differential amplifier comprising transistors (TRs) Q1, Q2, a TRQ3 of a smoothing time constant changing means is not conductive by selecting a DC voltage of a base bias terminal 5 of a TRQ4 and a resistor R3. When the AM signal is inpressed to the terminal 1, the TRQ1 is conductive, a signal voltage is produced at the resistor R3, the TRs Q3, Q4 are conductive and a capacitor C1 is charged with the sum of collector currents Ic3, Ic2 of the TRs Q2, Q3. The state of Ic3>>Ic2 is obtained by selecting suitably the base bias voltage of the TRQ4 and the charging time of the C1 is almost depending on the Ic3. Thus, the resistor R2 is selected to a large value, and the DC voltage smoothed sufficiently is led out at a control signal output terminal 4 without increasing the C1, and the excellent AGC characteristic is obtained even if the AM signal is subjected to a sudden change.
