Abstract

L'invention concerne un procédé et un circuit de production d'un signal de pseudo-erreur dans une unité de supervision de taux d'erreur. Un premier discriminateur régénère des premières données numériques à la sortie d'un démodulateur; un circuit d'extraction de bruit extrait une composante de bruit du signal d'entrée et un circuit additionneur additionne les signaux de sortie du circuit d'extraction de bruit et du circuit démodulateur. Un second discriminateur régénère des secondes données numériques à la sortie du circuit additionneur et une porte OUEXCLUSIF délivre un signal de pseudo-erreur si les premières données numériques ne coïncident pas avec les secondes. L'invention s'applique notamment à des dispositifs de transmission par modulation à déplacement de phase.
