Abstract
A method for communication by means of a transformer, which has at least a primary coil and a secondary coil, which are parts of an oscillatory circuit, wherein the oscillatory circuit is supplied on the primary side with an exciter frequency. For transmission of a signal from the secondary side to the primary side, the inductance of the secondary coil is modulated. A corresponding apparatus for performing the method is likewise provided.
