Verfahren zur Datenratendetektion und Datenratendetektor sowie Verfahren zur Regelung einer Phasenregelschleife und Phasenregelschleife

摘要

The invention relates to a method and a detector (11) for data rates for detecting data rates of a binary data stream with a plurality of edge changes that are provided with a mean edge changing rate with known edge change probability. The invention is characterised in that the means edge changing rate of the data stream (D) is compared to a mean edge changing rate of an additional data stream (TD). A signal (S1) is generated from the difference of both mean values. The signal (S1) is supplied to a phase-locked loop for coarse tuning of the oscillator (10).
