ABSTRACT:
Method for controlling an input signal for a contactless transponder, in which a signal strength of an amplitude-modulated input signal is controlled to a nominal value, and identification of a modulation gap by a demodulation device involves control for a controller gain at the time before the modulation gap being stipulated, and identification of the end of the modulation gap involves the control being released after a predetermined interval.
