    • 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.
    • 为了从干扰的输入信号产生未干扰的二进制输出信号,特别是如果后者在非干扰状态下是周期性的,本发明提出一种电路装置,其包括响应输入的不同边缘方向的两个电路分支 信号。 每个分支包括两个串联连接的触发器,并且还提供了两个电路分支通用的定时部件。 作为两个电路分支彼此耦合的结果,实现了在一个电路分支的触发之后,另一个分支被阻止。 只有在定时构件的延迟时间过去之后才可能触发另一个电路支路。 因此实现二进制输出信号的边缘具有最小时间间隔或二进制输出信号不超过最大频率。 此外,如果在延迟时间过去之前发生输入信号的转换,则也进行评估。 对两个电路分支中的信号进行评估可以形成两个不重叠的输出信号。
