Abstract

Ce dispositif fonctionne sans utiliser aucun organe mécanique A cet effet, le bouton de réglage 1 commandé à la main, entraîne un générateur tachymétrique 2 dont la sortie alimente, par l'intermédiaire du circuit oscillant RC 3, 4, un amplificateur 5 dont les impulsions de sortie transformées par un circuit convertisseur tension-fréquence 10, 11, 15 définissent suivant le sens et la valeur de la tension de sortie du générateur tachymétrique, le fonctionnement d'avance et de recul du compteur double 16 à directions de fonctionnement opposées. Ce dispositif est utilisable, en particulier, pour les générateurs synthétiseurs de fréquence.
