Abstract
L'invention concerne un module de détecteur d'onde d'impulsion dans lequel des signaux d'onde d'impulsion acquis par un capteur d'onde d'impulsion depuis deux bornes de sortie autres qu'une borne de mise à la terre, passent à travers deux filtres passe-haut qui sont connectés symétriquement via le même élément de circuit et à travers un premier amplificateur ou analogue, afin d'éliminer efficacement le bruit externe et d'amplifier les signaux d'onde d'impulsion faibles en signaux ayant une amplitude voulue. L'invention concerne également un appareil de mesure d'onde d'impulsion dans lequel le module d'onde d'impulsion ainsi configuré est disposé de manière à éliminer efficacement le bruit et à amplifier les signaux d'onde d'impulsion, et dans lequel le module de détecteur d'onde d'impulsion est monté séparément sur une seule carte de circuit imprimé de manière à faciliter l'utilisation et le remplacement de composant, et à mesurer des ondes d'impulsion de différentes manières.
