 EMI2.1 
 Kapazität B an das Erdpotentialglied 16 und an die Erdverbindung 22 angeschlossen sind, ist die Wirkung der Kapazität B aufgehoben. Die einzige wirksame Kapazität A kann nur einen sehr geringen Teil des ankommenden Potentiales höherer Frequenz unwirksam machen ; der Stromkreis besitzt demnach für die   Spraahübertragung   wertvolle Eigenschaften. 



   Statt des dargestellten Übertragers mit auf die Schenkel eines rechteckigen Rahmens aufgebrachten Teilwirkungen, der sogenannten Kerntype, kann auch der Übertrager der Manteltype (Manteltransformator) zur Anwendung kommen, bei der die Wicklungen auf einem Mittelschenkel in axialer Aneinanderreihung liegen. Statt der hier   geschilderten-Primär-und Sekundärwiclungen aus-je   einem Paar von Abteilungen kann jede der Wicklungen im Rahmen der Erfindung auch aus einer einzelnen oder aus einer Mehrzahl von Teilen bestehen. 



   PATENT-ANSPRÜCHE :
1.   Übertragerschaltung   mit einem Kerntransformator, dessen   Primär-und Sekundärwicklungen   je eine Mehrzahl von Lagen aufweisen, dadurch gekennzeichnet, dass die Verbindungen der Primär-und Sekundärspulen (5, 7) des einen Schenkels   (3)   so angeordnet sind, dass ihre einander benachbarten Lagen der Windungen Erdpotential aufweisen.

 EMI2.1
 Capacitance B are connected to the earth potential member 16 and to the earth connection 22, the effect of the capacitance B is canceled. The only effective capacitance A can only make a very small part of the incoming higher-frequency potential ineffective; The circuit therefore has valuable properties for the transmission of speech.



   Instead of the shown transformer with partial effects applied to the legs of a rectangular frame, the so-called core type, the transformer of the jacket type (jacket transformer) can also be used, in which the windings are axially aligned on a center leg. Instead of the primary and secondary windings described here, each consisting of a pair of compartments, each of the windings within the scope of the invention can also consist of a single part or a plurality of parts.



   PATENT CLAIMS:
1. Transmitter circuit with a core transformer, the primary and secondary windings of which each have a plurality of layers, characterized in that the connections of the primary and secondary coils (5, 7) of one leg (3) are arranged so that their adjacent layers of the windings have earth potential.
