To lock a control voltage to a voltage-controlled oscillator (1) in correspondence with a desired frequency (fref), a comparator (7) compares the output frequency (fvco) of the voltage-controlled oscillator (1) with the desired frequency (fref). A signal is generated in response to any frequency difference to adjust the control voltage until the frequency difference is zero. A copy of the control voltage is generated at least when said frequency difference is zero, and this generated copy is applied as control signal to the voltage-controlled oscillator (1) to lock its output frequency at the desired frequency (fref).
Pour verrouiller une tension de commande alimentant un oscillateur à fréquence commandée (1) conformément à une fréquence recherchée (f¿ref?), on utilise un comparateur (7) qui compare la tension de sortie (f¿vco?) de l'oscillateur à fréquence commandée (1) à la tension recherchée (f¿ref?). Tout écart de fréquence entraîne la production d'un signal destiné à ajuster la tension de commande jusqu'à ce qu'il n'y ait plus de différence de fréquence. Une copie de la tension de commande est produite au moins lorsque ledit écart de fréquence est nul, cette copie de tension étant ensuite appliquée comme signal de commande à l'oscillateur (1) de manière à verrouiller sa fréquence de sortie sur la fréquence recherchée (f¿ref?).
