    摘要: A method for demodulating a voltage which has been ASK modulated by changing the amplitude between a low level and a high level, in particular for use during contactless data transmission from a card reader/writer to a smart card, is described. The method is distinguished, in that, in an initialization phase, a first mean value is produced from the high voltage level and a stored partial voltage derived therefrom in order to detect a change to a low voltage level. The change to the low voltage level represents a start value and is detected by a subsequent comparison of the modulated voltage with the first mean value. In a subsequent demodulation phase, a second mean value is produced from the detected low voltage level and the high voltage level in order to demodulate the modulated voltage by comparing the modulated voltage with the second mean value.

    摘要: A data transmission circuit having a station and a response circuit. The station has an amplitude demodulator as well as a primary coil with a signal generator for producing an alternating magnetic field at a carrier frequency. The response circuit has a secondary coil as well as an amplitude modulator for influencing a load on the secondary coil, and the amplitude modulator is configured such that the alternating magnetic field can be modulated with a data signal. Particularly when the data transmission circuit is mass-produced, situations frequently occur in which the data signal modulated onto the alternating magnetic field by the response circuit can no longer be reconstructed at the station end. The object of the invention is thus to provide a data transmission circuit of this generic type, which always operates reliably. According to the invention, the response circuit has a phase modulator for influencing the electrical characteristics of the secondary coil. The amplitude modulator and/or the phase modulator being configured such that it or they can be driven, in particular, by at least one activation signal.

    摘要: A method for transmitting data between a terminal and a portable data carrier over a wire-free electromagnetic transmission link using a carrier signal which is 100% ASK-modulated in accordance with the data. The carrier signal serving as a clock signal for the portable the data carrier. The significance of an item of data is determined by a position of a shift keying point in the carrier signal within a time slot. The information content of the shift keying point corresponds to a number of N bits, N being greater than or equal to 2. The significance of the N bits is defined by a position of the shift keying point within 2.sup.N possible positions within the time slot. At the start or at the end of a time slot there is a zero time period in which no shift keying point which is assigned to the data to be transmitted occurs, in order to avoid an unacceptably long loss of the carrier signal.
