Abstract

L'invention concerne un appareil de mesure et d'analyse de signaux électriques. Il comprend un micro-processeur qui fonctionne en accord avec un programme mémorisé dans une mémoire pour produire un signal de sortie qui représente la surface des pointes du signal. Le signal de sortie peut être utilisé pour présenter l'information résultante par exemple sous forme imprimée. Un programme modifié peut être prévu pour être choisi si on désire que le signal de sortie représente la hauteur des pointes du signal. L'appareil est particulièrement utile pour l'analyse de signaux variables.
