Abstract

Et apparat for overvåkning av signalkvalitet i en kommunikasjonsforbintdel- se (2) omfatter midler (3) for å gjenkjenne tale-elementer i signaler som mottas over kommunikasjonsforbindelsen (2), og for å generere fra disse et estimat av det opprinnelige talesignalet, samt sammenlikningsmidier (8) for å sammenlikne det estimerte signalet med det faktiske mottatte signalet for å tilveiebringe et utgangssignal basert på sammenlikningen.
