Abstract
L'invention concerne la régulation du niveau d'un signal Pour réguler le niveau d'un signal au niveau d'une charge externe, on transmet ce signal par un atténuateur par bonds, 11, qui est commandé par un signal de réaction 13 provenant de la charge, par l'intermédiaire d'un circuit d'échantillonnage d'amplitude 14 et d'un circuit logique de commande 16. Application à la régulation du niveau des signaux de télécommande de basse fréquence injectés sur un réseau de distribution d'énergie électrique.
