Abstract
A method for the contactless transmission of at least one differential signal between a transmitter and a receiver given the existence of at least one common-mode noise signal, which has a low frequency in comparison with at least one signal to be transmitted, is provided. The suppression of at least one common-mode noise signal within the receiver a ground reference potential assigned to the receiver is separated into two ground reference potentials decoupled from one another. At least one common-mode noise signal may be suppressed by a filter unit at the input of a receive amplifier of the receiver.
