Circuit arrangement for converting an alternating-current signal into a binary signal

摘要

This circuit arrangement is needed when the clock in standard frequency systems is to be conditioned in such a manner that digital chips can be driven. At the same time, the alternating current signal is to be monitored. It is proposed to use a standard or HCMOS Schmitt trigger for converting an alternating-current signal into a square wave signal of the correct frequency and to combine the latter logically with a signal of another Schmitt trigger which, at the same time, is used for monitoring. Standard frequency systems.
