Abstract

a. Montage pour transformer des signaux analogiques en signaux numériques et inversement. b. Dans le cas où les signaux de somme reçus d'une liaison de conférence contiennent la partie propre d'un abonné, le signal numérique émis est mémorisé, est transformé en une valeur analogique et est soustrait du signal de somme reçu et transformé en une valeur analogique. c. Application aux installations téléphoniques à multiplexage par répartition dans le temps et à postes auxiliaires.
