Abstract
In order to generate a non-disturbed binary output signal from a disturbed input signal, notably if the latter is periodic in the non-disturbed state, the invention proposes a circuit arrangement which includes two circuit branches which respond to different edge directions of the input signal. Each branch includes two series-connected flipflops and there is also provided a timing member which is common to the two circuit branches. As a result of a coupling of the two circuit branches to one another it is achieved that, after the triggering of one circuit branch, the other branch is blocked. Triggering of the other circuit branch is possible only after the delay time of the timing member has elapsed. It is thus achieved that the edges of the binary output signal have a minimum temporal spacing or that the binary output signal does not exceed a maximum frequency. Furthermore, a transition of the input signal is evaluated also if it occurs prior to the elapsing of the delay time. Evaluation of the signals in both circuit branches enables formation of two non-overlapping output signals.
