摘要： In a method of transferring data from a transponder to a reading device in a scanning identification system through load-modulation of an inquiry signal emitted by the reading device, with the transponder being initialized at the beginning of the reception of the inquiry signal and responding with the emission of the response signal, first a predetermined number of data bits that are not part of the response signal are transmitted, and a terminator sequence followed by the response signal are repeatedly transmitted, until the inquiry signal is interrupted. The time required by the reading device for building up the inquiry field is bridged by the predetermined number of data bits and, at the same time, the reading device is synchronized to the clock of the response signal. Through the terminator sequence, which indicates the beginning of a valid response signal, the response signal is already recognized correctly by the reading device during the first transfer.

摘要： A receiver circuit, application of a first proportional element and a second proportional element of a digital PLL structure, and method for receiving a frequency-shift keyed signal are provided. A phase signal is calculated from an in-phase signal and a quadrature signal. A feedback signal is subtracted from the phase signal to form a difference signal. An output signal is determined from the difference signal by a nonlinear transfer function. The output signal is evaluated with an evaluation circuit. A first signal and a second signal are added to form a summation signal. The first signal is produced by multiplication of the output signal or the difference signal by a first proportionality factor. The second signal is produced by multiplication of the output signal or the first signal or the difference signal by a second proportionality factor, followed by integration, and the feedback signal is produced by integration of the summation signal.

摘要： A method for controlling a receiver circuit and circuit with a receiver circuit and with a control circuit is provided, whereby a received signal is demodulated and filtered. An amplitude value of the demodulated and filtered signal is compared with thresholds of a window comparator. A zero crossing of the demodulated and filtered signal is compared with time thresholds of a time window by a comparison unit. A first output value of the window comparator and a second output value of the comparison unit are logically combined, and wherein, via the logical combination, the receiver circuit is turned off if, within a period of time, the amplitude value is determined to be outside a window formed by the thresholds of the window comparator, or a zero crossing is determined to be outside the time window.
