Abstract

An arrangement for synchronizing a mechanical oscillating system to the accuracy of a quartz standard, in particular the timing of a clock. Timing pulses are derived from a quartz oscillation, and these act on the frequency of the oscillating system. An "existing value" signal is derived from the oscillating system, and frequency deviations of the existing value signal from the timing pulses are detected by a phase comparison. The frequency of the mechanical oscillating system is processed in accordance with the deviations that are detected.
