Abstract

Das Verfahren und die Einrichtung dienen zur Demodulation eines empfangenen Eingangssignals (E1), das ein aufmoduliertes Datensignal (D) umfasst. Das Eingangssignal (E1) wird mit einem Vergleichssignal (V) zu einem Zwischenfrequenzsignal (ZF1) gemischt, aus welchem ein aufbereitetes Zwischenfrequenzsignal (ZF2) erzeugt wird. In einer Kontrolleinheit (6) wird aus dem aufbereiteten Zwischenfrequenzsignal (ZF2) insbesondere mittels einer Abtastung das Datensignal (D) rückgewonnen. Das für die Mischung verwendete Vergleichssignal (V) und insbesondere auch ein für die Abtastung verwendetes Abtastsignal (A1) sowie ein dem Eingangssignal (E1) zugrundeliegendes Sendesignal (S1, S2) werden aus dem zur Takt-Versorgung der Kontrolleinheit (6) vorgesehenen Taktsignal (T) abgeleitet. Dadurch wird nur ein einziger Taktgenerator (16) benötigt.
