METHOD FOR RECONSTRUCTING DATA PULSED WITH A SYMBOL RATE FROM AN ANALOG DISTORTED SIGNAL

摘要

The invention relates to a method and a device for reconstructing data pulsed with a symbol rate from a signal which was distorted as a result of transmission over a transmission link, wherein the inventive method or the device is preponderantly carried out by means of digital circuit technology or consists of said technology and is designed to improve the quality of data retrieval. The inventive method involves amplifying the signal amplitude attenuated by the transmission; filtering high frequency noise frequencies above the symbol rate; discretizing the analog signal by means of an analog/digital converter (3); executing cable approximation by means of a digitally configured cable approximation filter (7) in order to obtain an equalized signal and recovering the data from the equalized signal using a phase locking loop (20).
