Abstract

Dispositif de surveillance et de correction de signaux, comportant une multiplicité de canaux de signaux, qui transmettent des signaux comparables entre eux, et qui sont raccordés par l'intermédiaire d'un formateur de valeur moyenne à un dispositif d'exploitation et de correction. Le formateur de valeur moyenne et un circuit de mise en mémoire de signaux sont montés l'un derrière l'autre et, avec au moins un canal de signaux transmettant un signal à surveiller, sont raccordés à un dispositif comparateur dans lequel on forme comme critère de surveillance la différence entre au moins un signal à surveiller et un signal de valeur moyenne mis en mémoire.
