Abstract

Zum Rekonstruieren von über eine Übertragungsstrecke, beispielsweise ein Kabel, übertragenen Daten wird das entsprechende von dem Empfänger empfangene Signal zunächst verstärkt und anschließend mit Hilfe eines Analog/Digital-Wandlers (6) diskretisiert, um ein entsprechendes digitales Signal zu erhalten, wobei hierzu das verstärkte Signal mit einer relativ geringen Abtastrate, welche im Bereich der Nyquistfrequenz liegen oder sogar kleiner als die Nyquistfrequenz sein kann, abgetastet wird. Anschließend wird das auf diese Weise diskretisierte Signal mit Hilfe eines digitalen Hochpass-Filters (8) gefiltert und mit Hilfe eines digitalen Kabelapproximations-Filters (9) zur Kompensation der während der Übertragung über die Übertragungsstrecke auftretenden Verzerrung entzerrt. Aus diesem derart aufbereiteten digitalen Signal wird mit Hilfe eines Phasenregelkreises (14, 18) ein regenerierter Takt (CLK) und synchron zu diesem Takt die ursprünglich übertragenen Daten (DATA) gewonnen.
