Circuit arrangement for evaluating pulses

摘要

In this circuit arrangement, in which an output signal is to be output when a pulse or a sequence of pulses exceeds a predetermined duration during a predetermined measuring period, a counter is connected at the output end to a comparator which can be supplied with a predetermined count. The output signal can be picked up at an output of the comparator. The counter can be supplied with a clock signal in dependence on an enable signal and a reset signal which can be derived from the pulses with the aid of a switch-over device.
