Abstract

Dans un montage d'amplificateur de signal d'affichage, un circuit ampèremétrique (S) mesure un courant d'alimentation d'un amplificateur (A) de façon à retrouver le signal de commande (CTRL) destiné à un réducteur de largeur de bande (BRC) précédant l'amplificateur (A). Le réducteur de largeur de bande (BRC) a pour fonction d'atténuer en mode adaptatif une composante HF du signal d'affichage en fonction du courant d'alimentation.
