Anotation

Deals with baseband-to-baseband measurements of the noise performance of simulated radio-relay systems used for frequency division multiplex telephony. These measurements are additional to those already given in Part 3, Section Three of IEC 60487-3-3. Traite de mesures pour la transmission de la telephonie multivoie a multiplexage par repartition en frequence (m.r.f.). Les mesures sont effectuees de bande de base a bande de base au moyen dun signal modulant a spectre continu uniforme. Leur but est la determination de la qualite de transmission dune liaison simulee. Ces mesures sont complementaires a celles deja decrites dans la CEI 60487-3-3, section trois.
