Abstract
Monolithic realizations of general telecommunications systems require high-performance internal circuits. To achieve these results digital and analog solutions are available. The general trend is toward digital implementations which guarantee high density and easy design. However, in each overall system there are some blocks requiring necessary an analog solution. Furthermore the entire system performance is often strictly dependent on the performance of the analog section. In this paper the role of analog blocks in three telecommunications systems (ISDN, line card and telephone set) is described.
Résumé
Trois exemples illustrent ľ emploi de circuits intégrés analogiques: blocs rnis tels que le bloc ďinterface U, qui connecte la ligne ďabonné à deux fils avec ľenvironnement à quatre fils de chaque côté et le bloc dit « Combo » (codec-filtre); carte de ligne combinant celui-ci et le joncteur ďabonné (SLIC); poste téléphonique.
