摘要： In a bi-directional contactless data transmission, a procedure aims to prevent the communication distance from being extended by unauthorized persons using radio repeaters. The procedure involves establishing a fixed relationship of a selected physical parameter of an electromagnetic signal. For example, the frequency of the signal received by a transponder is multiplied with a number to provide a different frequency, and a response signal having this different frequency is transmitted back to a base unit. In the base unit, the received frequency of this response signal is divided by the same number and the result is compared to the frequency of the originally emitted signal. If the resulting difference is below a preset threshold, then there is a fixed frequency relationship between the two signals, the process concludes that there has been no unauthorized extension of the communication distance by using repeaters, and the further authentication is carried out.

摘要： In a method of detecting redirection or interception during a bi-directional non-contact making data transmission, the attenuation (A1) of the amplitude over the forward path is compared with the attenuation (A2) of the amplitude over the return path. The attenuation (A1) over the forward path is transmitted in encoded form with the reply signal. If the attenuation values determined thereby are of the same magnitude, then the likelihood of a redirecting process can be excluded. In order to additionally increase the security of the system, the carrier frequency (F2) of the interrogation signal can also be compared with the carrier frequency (F21) of the reply signal. The signals can also incorporate an ID code.

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.

摘要： A receiving unit including an operational amplifier having a fixed gain receives an electromagnetic signal, from which a voltage divider with a variable resistance generates an input voltage for the amplifier. The amplifier's output voltage is compared with a reference voltage. The variable input resistance is adjusted to vary the amplifier's input voltage, until the amplifier's output voltage lies within a defined range around the reference voltage. This adjusted resistance value is compared with nominal resistance values previously stored in a value field and respectively allocated to field strength values, to determine a field strength of the received signal. A circuit arrangement includes an operational amplifier, a memory unit connected to a processor unit, a first voltage divider, a second voltage divider, and a control element that controls the second voltage divider to provide the controlled variable input resistance. The processor unit reads the control state of the control element to determine the adjusted input resistance, and therefrom determines the field strength value of the received signal.
