Title (EN) CIRCUIT AND METHOD FOR GALVANICALLY SEPARATE BROADBAND TRANSMISSION
(FR) CIRCUIT ET PROCEDE DE TRANSMISSION A LARGE BANDE GALVANIQUEMENT SEPAREE
(DE) SCHALTUNGSANORDNUNG UND VERFAHREN ZUR GALVANISCH GETRENNTEN BREITBAND-ÜBERTRAGUNG
Abstract:
(EN) The aim of the invention is to provide a simple and economical means of galvanically separately transmitting data signals. To this end, the data signals are superimposed on a clock signal in an input stage and galvanically separately transmitted to an output stage by means of a decoupling device. The part of the clock signal on which the transmitted signals are superimposed is filtered out in the output stage. The pulse shape changes in the transmitted signals resulting from the galvanically separate transmission or the clock signal being filtered out are also compensated in the output stage, leaving filtered data signals at the output of the circuit.
(FR) L'invention concerne une transmission galvaniquement séparée de signaux données. Pour que cette transmission galvaniquement séparée soit simple et économique, ces signaux données sont superposés à un signal de synchronisation dans un étage d'entrée et sont transmis par un dispositif de découplage à un étage de sortie de façon galvaniquement séparée. Dans l'étage de sortie, la fraction du signal de synchronisation à laquelle les signaux transmis sont superposés, est extraite par filtration. Les modifications de forme d'impulsion des signaux transmis sont également égalisées dans l'étage de sortie par la transmission galvaniquement séparée ou par l'extraction par filtration du signal de synchronisation de telle façon qu'il y ait à la sortie du circuit des signaux données filtrés.
(DE) Um eine einfache und kostengünstige galvanisch getrennte Übertragung von Datensignalen zu ermöglichen, werden diese in einer Eingangsstufe einem Taktsignal überlagert und über eine Entkopplungseinrichtung galvanisch getrennt an eine Ausgangsstufe übertragen. In der Ausgangsstufe wird der Anteil des Taktsignals, dem die übertragenen Signale überlagert sind, weggefiltert. Impulsformveränderungen der übertragenen Signale durch das galvanisch getrennte Übertragen oder durch das Wegfiltern des Taktsignals werden in der Ausgangsstufe ebenfalls ausgeglichen, so daß am Ausgang der Schaltungsanordnung gefilterte Datensignale anliegen.
