Abstract:
An electronic circuit arrangement for receiving low-frequency electromagnetic waves is proposed, having an inductor (L) acting as an antenna for generating a received signal, having a first receiver (2), connected to the inductor (L), for decoding a first component of the received signal and having a second receiver (3), connected to the inductor (L), for decoding a second component of the received signal, wherein at least the second receiver (3) is connected to the inductor (L) via an attenuator element (4) having adjustable attenuation, wherein at least one adjustment signal generation circuit (5, 6) is provided for generating an adjustment signal corresponding to a voltage of the received signal which is fed to the attenuator element (4) for adjusting the attenuation.
