Abstract

PROCEDE POUR SUPPRIMER LES PERTURBATIONS RECIPROQUES EN CAS DE PLUSIEURS SYSTEMES TRAITANT DES IMPULSIONS OU PRODUISANT DES IMPULSIONS FONCTIONNANT EN MEME TEMPS ET DANS LESQUELS LES IMPULSIONS PROPRES ETOU DES IMPULSIONS ETRANGERES SONT CAPTEES DANS UN INTERVALLE DE TEMPS DE TRAITEMENT PLUSIEURS FOIS REPETE. LA DISTINCTION ENTRE LES IMPULSIONS ETRANGERES ET LES IMPULSIONS PROPRES S'EFFECTUE SUR LA BASE DE CARACTERISTIQUES DE FREQUENCES EN CE QUI CONCERNE LA COINCIDENCE ENTRE L'INTERVALLE DE TEMPS DE TRAITEMENT ET LES IMPULSIONS ARRIVANT.
