Document Type and Number:
Japanese Patent JP2001502145
Kind Code:
A
Abstract:
The invention concerns a data-transmission circuit with a station (1) and a response circuit (2), the station comprising a primary coil (4) with a signal generator (3) for generating a magnetic alternating field at a carrier frequency, and an amplitude demodulator (6). The response circuit (2) comprises a secondary coil (7) and an amplitude modulator (13) for influencing the load on the secondary coil. The amplitude modulator (13) is designed such that the magnetic alternating field can be modulated by a data signal.
