Abstract

L'invention concerne les atténuateurs commandés en tension. Un atténuateur à structure symétrique comprend essentiellement des convertisseurs de sommation 12, 14 qui ajoutent au signal d'entrée une tension continue de point de repos; des cellules de gain 24, 26, commandées par une source de tension de commande 28, des amplificateurs séparateurs 36, 42, et un amplificateur différentiel 42 qui combine les signaux de sortie des amplificateurs 36 et 40. Application aux atténuateurs télécommandés.
