    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 invention relates to a method for retrieving a digital data stream (301) according to which a reference pulse phase (308) is retrieved from the digital data stream (301). Said digital data stream (301) is received in a data stream receiver (302) and is low-pass filtered in a low-pass filtering device (303). An edge position signal (309) is determined in an edge position detection device (304), through comparison of an amplitude of the low-pass filtered data stream (305) with a settable threshold value (108). A phase deviation (111a) is determined in a phase correction system (307) from a time difference between a 0/1-threshold value intersecting point (109) of the threshold value (108) with a 0/1- data transfer (101) or a 1/1-threshold value intersecting point (110) of the threshold value (108) with a 1/1 data transfer (102) and the target time of the control (310), so that the phase deviation (111a) can be corrected with the phase correction offset (111b) in the phase correction system (307).

    Abstract: Generator signals are generated by unit (10), providing signals with certain signal form determined in dependence on preset signal norm form. Matching unit (20) adapts generated signal form to properties of signal transmission channel. Signal generating and matching units are so fitted that signals transmitted, via transmission channel, from matching unit are in signal form corresponding to preset signal norm form. Signal matching and generating units are of digital type.

    Abstract: A method for synchronizing a clock signal with a reference signal is disclosed. One embodiment has a first synchronization part which has a bit pattern having a particular clock period, a pause whose length is a multiple of this clock period plus a fraction of the clock period, and a second synchronization part having the particular clock period. The method includes generating a phase difference signal which is proportional to a phase difference between the clock signal and the reference signal, filtering the phase difference signal and providing a filtered phase difference signal, driving a digital oscillator in such a manner that the frequency of the clock signal is changed on the basis of the filtered phase difference signal, the phase of the clock signal within a clock period being corrected by a value corresponding to the fraction of the clock period at an end of the pause in the reference signal.

    Abstract: A phase-monitoring circuit (18) generates a phase difference signal to show the phase difference between a received signal and a regenerated output signal for a phase locked loop (PLL) circuit (17). A loop filter (1) filters the phase difference signal that has been generated. An oscillator (27) controlled by the filtered phase difference signal generates an output signal for the PLL circuit. Independent claims are also included for the following: (a) A method for eliminating inherent jitter in a signal received from a control circuit; (b) and for a signal processor for carrying out the method of the present invention.

    Abstract: Eine Schaltung zum Betreiben von Lautsprechern umfasst eine erste, zweite, dritte und vierte Lautsprecherschaltung, mit je einem Eingang zum Einprägen eines Signals und je einem Ausgang zum Anschließen eines Lautsprechereingangs, wobei die Lautsprecherschaltungen dazu ausgebildet sind, das eingeprägte Signal zu verstärken und das verstärkte Signal an ihren Ausgängen bereitzustellen. Die Lautsprecherschaltungen können beispielsweise für ein 2.1 Soundsystem verwendet werden. Die 3 Kanäle für ein 2.1 Soundsystem können mit einer Verstärkerschaltung mit 4 Lautsprecherschaltungen realisiert werden, wobei für die beiden Stereokanäle links und rechts jeweils eine Lautsprecherschaltung benötigt wird. Ein Subwooferkanal kann mit 2 Lautsprecherschaltungen differentiell angesteuert werden. Die Stereokanäle sind hingegen nur noch mit jeweils einer Lautsprecherschaltung verbunden, so dass die Stereokanäle zumindest ein weiteres gemeinsames Massekabel benötigen.
