摘要：Using this device, the sensitivity in receivers, the gain control criterion of which isa constant noise signal, can be controlled independently of received information signalsso that the reception of information flows lasting a long time is possible. For thispurpose, a diode (D1) is provided which is connected with its anode to a voltage sourceand is connected with its cathode, on the one hand, to a current source (Q4) and, on theother hand, to the cathode of another diode (D2), the anode of which is connected to the

capacitor (C12). A first voltage which is lower in the no-signal state than a second voltagesupplied via the one diode (D1) is present across the capacitor (C12) so that the furtherdiode (D2) is blocked. After an information signal has been received, a discharge pulse(EP), by means of which the second voltage is lowered to a value which is lower than thefirst voltage, is generated in dependence on an output signal of a signal detector. In thisprocess, the capacitor (C12) is discharged to such an extent that the amount of chargelost corresponds to the charge applied to the capacitor (C12) when an information signalis received.
