Abstract

L'INVENTION CONCERNE UN CIRCUIT DE COUPLAGE VIDEO A COURTE CONSTANTE DE TEMPS. IL COMPORTE DES AMPLIFICATEURS D'ENTREE ET DE SORTIE INTERCONNECTES PAR UN CIRCUIT RC COMPRENANT UN CONDENSATEUR EN SERIE ET UNE SOURCE DE COURANT CONSTANT EN DERIVATION. L'INTENSITE DU COURANT QUI CIRCULE DANS LA SOURCE EST REGLEE AU MOYEN D'UNE SOURCE ELOIGNEE DE TENSION CONTINUE REGLABLE. L'INVENTION S'APPLIQUE NOTAMMENT AUX RECEPTEURS RADAR.
