An echo canceller comprising a digital filter having adaptive coefficients which are updated to simulate an echo response, a temporary register for storing default coefficients, and a controller for monitoring ERLE and in the event the ERLE is greater than a first predetermined threshold then enabling the digital filter and replacing the default coefficients in the temporary register with the adaptive coefficients, and in the event the ERLE is less than a second predetermined threshold then disabling the digital filter and replacing the adaptive coefficients with said the default coefficients from the temporary register.

Un suppresseur d'écho comprenant un filtre numérique ayant des coefficients adaptatifs qui sont mis à jour afin de simuler un retour d'écho, un registre temporaire pour stocker des coefficients par défaut, et un contrôleur pour la surveillance du retour d'écho ERLE et, dans le cas où l'ERLE est supérieur à un premier seuil prédéterminé, activant alors le filtre numérique et remplaçant les coefficients par défaut dans le registre temporaire avec les coefficients d'adaptation et, dans le cas où l'ERLE est inférieur à un deuxième seuil prédéterminé, désactivant alors le filtre numérique et remplaçant les coefficients adaptatifs avec lesdits coefficients par défaut dans le registre temporaire.
