ABSTRACT:
A circuit arrangement for clock pulse recovery on the receiving side of a digital clock-controlled data system is particularly characterized in that in the receiver a branch circuit is connected to the input side in parallel with a digital converter for converting the digital data signal, the branch circuit comprising an EXCLUSIVE or gate having two inputs and a delay element in the feed to one input of a digital counter which is connected to the output of the EXCLUSIVE OR gate and actuated by a quartz-stabilized oscillator having a frequency of multiple of the desired timing frequency and whose output is connected to the digital converter.
