Abstract

On décrit un circuit de conditionnement de signaux pour détecter les passages par zéro de la sortie d'un capteur à inductance ou à réluctance variable, comprenant un circuit (20, 30) pour transformer le signal de sortie du capteur en un signal ayant une amplitude sensiblement indépendante de la fréquence et de la même fréquence que celle du signal de sortie du capteur, ainsi qu'un circuit (40) pour détecter les passages par zéro du signal de sortie transformé. Le circuit de transformation du signal de sortie du capteur comporte un comparateur (30) pour comparer la valeur instantanée du signal de sortie du capteur avec un signal de référence, un circuit d'intégration pouvant être remis à zéro (20) muni d'un condensateur de stockage (26) pour intégrer la sortie du capteur par rapport au temps, et un moyen de commutation électronique (26) pour remettre à zéro le circuit d'intégration par la décharge du condensateur de stockage (24).
