The invention relates to a circuit arrangement for noise pulse extraction. To extract noise pulses from receive circuits of telegraphy terminals, the delay time for the evaluation of received character steps is determined by the charging and discharging of a capacitor; at the end of the evaluation process, additional, low-impedance charging or discharging circuits are connected and the recharging time of the capacitor is considerably reduced (Fig. 1). The circuit arrangement is used primarily in connection systems for telegraphy and data terminals.
