Abstract

Circuit de mesure de signaux électriques par intégration, dans lequel l'étage intégrateur des signaux est relié alternativement à un étage de charge t à un étage de décharge. Ce circuit comprend une ligne à retard insérée entre la sortie de l'étage intégrateur et l'entrée de l'étage de décharge, afin de lier la valeur du courant de décharge à une valeur constante de tension pendant cette décharge. Ce circuit peut aussi comprendre un circuit de temporisation garantissant que cette valeur constante de tension sera maintenue pendant une durée suffisante. Ce circuit peut enfin comprendre un circuit d'avance à l'ouverture du commutateur de décharge, afin de tenir compte du temps de transmission des signaux de commande d'ouverture vers ce commutateur de décharge. Application : Détection de signaux d'amplitude et de périodicité aléatoires, en gammagraphie notamment.
