摘要

A circuit arrangement for the automatic regulation of the frequency of an oscillator at a reference frequency, with a phase discriminator being generated by a regulation voltage, which governs an explorer oscillator acting on the reactance stage of the oscillator, so that the The oscillator scanner exceeds the pick-up area, automatically interrupting its activity at the time of synchronization, characterized in that the differential oscillation generated in the phase discriminator from the oscillation of the oscillator and the reference oscillation, load, through a rectifier, a capacitor located in the control circuit of a tilting circuit, and that on the reactance stage act, both the regulation voltage, fed through a resistance, as well as the voltage in the capacitor.
