1. A signal transmission arrangement, comprising:

  • a transformer having a first winding and a second winding, wherein the transformer is a coreless transformer;

    a damping circuit having an input terminal for receiving an input signal, the damping circuit coupled to the first winding and configured to have an electrical resistance that is dependent on the input signal;

    an oscillator circuit comprising the second winding and configured to provide an oscillating signal; and

    an evaluation circuit configured to receive the oscillating signal, and to provide an output signal that is dependent on an amplitude of the oscillating signal.
