Abstract

Dans un montage de filtre adaptatif pour déduire une mesure du degré de convergence, on compare une quantité d'adaptation se produisant dans le montage de filtre adaptatif pendant une période définie, à une valeur de référence résultant d'un cumul pendant la même période. A partir du degré de convergence indiqué, on peut décider d'avoir recours à un traitement supplémentaire du signal, de modifier ce traitement, ou de s'en dispenser.
