Abstract
Correction du signal d'un transducteur digital de mesure. Les variations de la fréquence des impulsions du transducteur en fonction d'une grandeur physique à mesurer peuvent être représentées par une droite qui, pour diverses raisons, ne passe pas par l'origine. En superposant, c'est-à-dire en ajoutant ou en soustrayant des impulsions de correction à des impulsions du transducteur, ladite droite est déplacée et peut ainsi passer par l'origine, la fréquence des signaux émis par le transducteur devenant ainsi proportionnelle à la grandeur physique à mesurer. Instruments de mesure, débitmètres, à transducteur digital, etc.
