Abstract

DISPOSITIF DE CONTROLE AUTOMATIQUE DU GAIN D'UNE VOIE DE RECEPTION DANS UN SYSTEME COMPORTANT DES LIAISONS OPTIQUES A TRES LARGE BANDE PASSANTE. LE SIGNAL UTILE DE NIVEAU INCONNU EST TRANSMIS AVEC UN SIGNAL PILOTE DE NIVEAU CONNU A TRAVERS UNE LIAISON OPTIQUE OU IL SUBIT UNE ATTENUATION, VERS UN ENSEMBLE DE RECEPTION CONNECTE AU TRANSDUCTEUR OPTO-ELECTRONIQUE DE SORTIE DE LA VOIE OPTIQUE. UN DISPOSITIF DE CONTROLE DU GAIN DE LA VOIE DE RECEPTION COMMANDE PAR LE SIGNAL PILOTE COMMANDE EN NUMERIQUE UN CIRCUIT D'ATTENUATION QUI DELIVRE ENSUITE LE SIGNAL UTILE RETABLI A SON NIVEAU INITIAL. APPLICATION AU DOMAINE DE L'ELECTRONIQUE RAPIDE.
