Method and device for crosstalk compensation

A signal processing unit comprising:

• (a). at least one measured data signal input line adapted to receive a measured data signal generated by an image current, wherein the measured data signal comprises an added crosstalk signal induced by a source of electromagnetic disturbance;
• (b). at least one disturbance signal input line adapted to receive a decoupled disturbance signal, extracted from the source of electromagnetic disturbance by an extraction device;
• (c). an output line adapted to supply a compensated data signal to at least one data receiving device;
• (d). a conditioning module, to which the decoupled disturbance signal is supplied via the disturbance signal input line and which provides a compensation signal;
• and
• (e). an adding module, to which the measured data signal and the compensation signal are provided and in which the measured data signal and the compensation signal are superposed,
• whereby the decoupled disturbance signal is conditioned by the conditioning module in such a way that the compensation signal essentially corresponds to an inverted added crosstalk signal.
