ABSTRACT:
A system for bringing the frequency of an oscillator under the control of the frequency of the carrier of a pulse wherein a parameter characteristic of the carrier frequency value is measured throughout the duration of the pulse, the measurement result is stored, the same parameter is measured in respect of the frequency to be controlled, and the control is carried out after the pulse by comparison of the second measured parameter with the first and stored measured parameter.
