Abstract
L'invention présente un dispositif combinant les fonctions d'oscillateur réglé par tension et de multiplicateur de fréquence. Ce dispositif comprend un nombre impair d'inverseurs 40-1 à 40-n montés en cascade pour former un anneau oscillant à une fréquence f1 et reliés à une source d'alimentation + VCC par l'intermédiaire d'un circuit accordé 46 créant un second signal à une fréquence multiple nf1 . Chaque étage est conçu pour puiser de l'énergie pendant une durée inférieure à la période du signal de l'anneau 18. L'invention s'applique à la télévision ainsi qu'à la radiodiffusion.
