Title
(DE) FILTER FÜR ELEKTROMAGNETISCH ÜBERTRAGENE SIGNALE
(EN) FILTER FOR ELECTROMAGNETICALLY TRANSMITTED SIGNALS
(FR) FILTRES POUR SIGNAUX A TRANSMISSION ELECTROMAGNETIQUE
Abstract
(DE)
Ein Filter für elektromagnetisch übertragene Signale, insbesondere für Signale an Mobiltelefone und dergleichen verbrauchergenutzte Endgeräte, wobei der Filter eine Hemmung störender Einflüssen gegenüber Daten enthaltenden Signale bewirkt, wird so ausgebildet, daß der Filter hinsichtlich seiner hemmenden Einflüsse an verschiedene Übertragungsparameter anpaßbar ist.
(EN)
The invention relates to a filter for electromagnetically transmitted signals, especially for signals of mobile telephones and similar user terminals. The filter inhibits and disturbing influences on data containing signals. The filter is configured to be adaptable to various transmission parameters in terms of its inhibiting effect.
(FR)
La présente invention concerne un filtre destiné à des signaux à transmission électromagnétique, notamment à des signaux de téléphones mobiles et terminaux utilisateur analogues. Selon l'invention, le filtre sert à inhiber les effets parasites agissant sur des signaux porteurs de données. Ledit filtre est formé de sorte qu'il peut adapter ses effets d'inhibition à différents paramètres de transmission.
