Abstract

Verfahren und Anordnung zur Erkennung von Gebührenimpulsen in einer Telefonanlage, die als impulsweise auftretende Schwingungszüge einer Schwingungsfrequenz übertragen werden, die über dem Sprachfrequenzband liegt. Um eine digitale Auswertung der Gebührenimpulse bei geringem Aufwand für die A/D-Wandlung zu ermöglichen, werden durch Modulation (5) mit Rechteckimpulsen modifizierte Gebührenimpulse (6) erzeugt mit niederfrequenten Spektralanteilen im Sprachband, welche die Umsetzung mit Hilfe preiswerter Coder (7) erlauben.
