Abstract:
A method of demodulating signals of an electromagnetic field induced by a contactless transponder includes a step in which the signals from the transponder are detected at given times or frequency. The times or frequency of the detection are synchronized in phase with the electromagnetic field. An associated demodulator and reader are also disclosed.
