Abstract

Perfections in automatic frequency control systems for oscillators, characterized in that they comprise a relatively low stabilized frequency generator; a phase detector; means for applying pulses of said generator, as an input, to said phase detector; means for applying oscillator oscillations, like the other input to the phase detector; a generator of direct current potential; a frequency control circuit, adapted to control the frequency of the oscillator as a function of a control power; means for, at will, storing and using as said control potential, either the output of the phase detector, or a potential of the indicated generator of dc potential, and means for applying pulses of the generator thereof, as closing pulses to the indicated oscillator, when the output of the phase detector is stored and used as said control potential.
