Abstract
The detection of short pulses of a digital input signal by an evaluation circuit, whose time intervals for polling the input signal are long compared to the duration of the pulses, is made possible by the formation of a difference between the input signal and an output signal formed from the input signal. A change in the output signal is effected proportionally to the difference with a large proportionality factor when the difference has a first operational sign, and proportionally to the difference with a small proportionality factor when the difference has another operational sign.
