    Abstract: 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).

    Abstract: The aim of the invention is to restore data transmitted via a transmission line, especially a cable. To this end, the corresponding signal received by the receiver is amplified, and the amplified signal is then discretised by means of an analog-digital converter (6) in order to obtain a corresponding digital signal. The amplified signal is then sampled at a relatively low scanning rate, said scanning rate being in the Nyquist frequency range, or even lower than the same. The signal which is discretised in the above manner is then filtered by means of a digital high pass filter (8) and is equalised by means of a digital cable approximation filter (9) in order to compensate the distortion occurring during the transmission via the transmission line. A regenerated clock pulse is obtained from the digital signal processed in this way, by means of a phase-locked loop (14, 18), and the originally transmitted data (DATA) is recovered synchronously with said clock pulse.

    Abstract: Es werden beispielhafte Implementierungen von elektrischen Schaltungen und Systemen und Verfahren zur Signalverarbeitung offenbart, darunter Abtasten und Quantisieren von amplituden- und bandbegrenzten Signalen, die durch einen Passiv-Pulsmodulations-Analog-Digital-Umsetzer (PMADC) implementiert werden. Die Umsetzerschaltung umfasst einen analogen Modulator. Der analoge Modulator (202) umfasst ein passives zeitkontinuierliches Filter (220) mit einem ersten passiven Teilfilter (334), das dafür ausgelegt ist, ein Analogsignal zu empfangen, einem zweiten passiven Teilfilter (336), das dafür ausgelegt ist, ein Rückkopplungssignal zu empfangen, und einem Summierungsknoten (338), der dafür ausgelegt ist, ein Ausgangssignal des ersten Teilfilters (334) mit einem Ausgangssignals des zweiten Teilfilters (336) zu kombinieren, um ein Ausgangssignal des Summierungsknotens (338) bereitzustellen. Der analoge Modulator (202) umfasst ferner einen Komparator (222), der dafür ausgelegt ist, das Ausgangssignal des Summierungsknotens (338) zu empfangen und eine Timing-Eigenschaft (Zeitverhalten- oder Takteigenschaften) eines Ausgangssignals des Komparators (222) auf der Basis einer Stärke des durch das erste Teilfilter (334) empfangenen Analogsignals zu variieren.

    Abstract: A test signal comprising several tones is generated in order to analyse the non-linear properties of a communications channel (2). The test signal is transmitted via the communications channel (2) and evaluated. Equidistant audio frequencies are then selected for the individual tones of the test signal. Not all of these audio frequencies are used for the test signal. Frequency shifters in the form of digital modulators (20-23) are used to shift the frequency spectrum of the test signal transmitted by an unused audio frequency value to zero, respectively. In this way, non-linear interference can be determined using a low-pass filter (24).
