Abstract

Des éléments (16, 18) par exemple des transformateurs, détectent des signaux de courant de tension. L'un de ces signaux analogiques est converti par un modulateur (30)en un premier signal modulé pouvant alterner entre deux niveaux à des premiers intervalles d'horloge. Domaine d'application : comptage de l'énergie électrique.
