Abstract

A digital circuit has a signal input terminal and a signal output terminal. The digital circuit additionally has a logic circuit unit, whose input is connected to the signal input terminal and whose output is connected to the signal output terminal via a switching element. Furthermore, it has a filter unit, whose input is connected to the signal input terminal and whose output is connected to a control input of the switching element. The filter unit serves for suppressing glitches on a digital signal present at its input.
