A device for determining the quality of an output signal originating from a signal processing circuit is provided with a first series circuit for receiving the output signal and with a second series circuit for receiving a reference signal and generates an objective quality signal by means of a combining circuit coupled to the two series circuits. The poor correlation between said objective quality signal and a subjective quality signal can be improved by inside the combining circuit comparing a differential signal which has been integrated with respect to frequency with a predefined value and then in dependence of a comparison result integrating it with respect to time or not, and/or comparing a quality signal associated with a left channel with a quality signal associated with a right channel and selecting the quality signal having the largest value and modifying it in dependence of integrated differential signals.

L'invention concerne un dispositif qui permet de déterminer la qualité d'un signal de sortie provenant d'un circuit de traitement de signaux. Le dispositif comporte un premier circuit série qui reçoit le signal de sortie et un second circuit série qui reçoit un signal de référence, et il génère un signal de qualité objective au moyen d'un circuit de combinaison couplé aux deux circuits séries. Pour améliorer la mauvaise corrélation entre ledit signal de qualité objective et un signal de qualité subjective, on compare à une valeur prédéfinie, à l'intérieur du circuit de combinaison, un signal différentiel qui a été intégré par rapport à la fréquence, puis, en fonction du résultat de la comparaison, on l'intègre ou non par rapport au temps; et/ou on compare un signal de qualité associé à un canal gauche à un signal de qualité associé à un canal droit, puis on sélectionne le signal de qualité ayant la plus grande valeur et on le modifie en fonction des signaux différentiels intégrés.
