Abstract

Übertragungsanordnung zur Übertragung von Signalen, insbesondere Mess- bzw. Steuersignalen, in analoger Form, mit einer Gleichstrom (DC)-D/A-Umsetzerschaltung (12') für ein DC-Nutzsignal, die einen Eingangsspeicher, z.B. ein Register (23), einen digitalen Modulator, insbesondere ΣΔModulator (57), und einen analogen Tiefpass (25') enthält, und mit einer Wechselstrom (AC)-D/A-Umsetzerschaltung (13') für ein moduliertes AC-Modemsignal, die einen digitalen Pulsweitenmodulator (62) und ein analoges Filter (33') enthält; in der DC-D/A-Umsetzerschaltung (12') ist dem digitalen Modulator ein digitales Tiefpassfilter (47) zugeordnet, in der AC-D/A-Umsetzerschaltung (13') ist dem Pulsweitenmodulator (62), der das Modemsignal in ein 1-Bit-Signal umsetzt, ein analoger Summierer (63) nachgeordnet, dem ein weiteres zu summierendes Signal, wie z.B. ein während des Ruhezustands aktiviertes Gleichstrom-Signal, ein MSB-Signal oder ein Taktsignal, zugeführt wird.
