Abstract

a. Procédé et installation pour convertir une fréquence ou une période, proportionnelle à une course, en une grandeur numerique de sortie dépendant de la course de façon non linaire; b. Procédé caractérisé en ce qu'on convertit en un nombre, au moyen d'un compteur, la fréquence f dont la période T est proportionnelle à la course S, alpha ou la période T dont la fréquence f est proportionnelle à cette course, et on forme le complément de ce nombre en tant que grandeur de sortie; c. L'invention trouve son application dans le domaine des moteurs à injection de carburant.
