Abstract

Ce circuit est destiné à éliminer les signaux parasites induits simultanément sur les deux conducteurs d'un support de transmission L dont l'un des conducteurs transmet un signal utile. Il comporte un amplificateur 1, R à entrée à très faible impédance (-) couplée à l'un des deux conducteurs du support L et un générateur de courant T, D, Rb, Rc couplé à l'autre conducteur du support de telle sorte que les signaux parasites dans le support produisent des courants de mêmes amplitudes et de phases opposées sur l'entrée à faible impédance. Ainsi, seul le signal utile est présent à la sortie VS de l'amplificateur 1, R. Application au transport de signaux en milieu pertubé. (CF DESSIN DANS BOPI)
