Abstract

In a circuit arrangement for telecommunications switching systems with locators (D) for information recording based on the last-look principle, AC noise voltages are identified with the aid of time-measuring devices (R, V, W). Received pulses are divided into useful pulses and noise pulses by means of time measurement. The respective duration of consecutive noise pulses or the respective duration of the pauses occurring between them or the respective period length is measured. The time values measured herein are compared with one another and checked in terms of definable periodicity. <IMAGE>
