Abstract: A signal-analyzing unit has a sampling path and a reference path both receiving a digital test signal. The sampling path has a first comparator for comparing the test signal against a first threshold value and providing a first comparison signal, and a first sampling device receiving as input the first comparison signal and a first timing signal. The reference path has a second comparator for comparing the test signal against a second threshold value and providing a second comparison signal, and a second sampling device for receiving as input the second comparison signal and a second timing signal. An analysis unit receives and analyzes the output of the sampling and reference paths.

Abstract: A data carrier for contactless communication with a communication station has a substrate and a communication resonant circuit connected to the substrate and consisting of a communication coil and of a capacitor configuration and having a resonant frequency which should have a nominal value, whereby enabling resonant frequency to be changed from an initial value both to higher frequency values and to lower frequency values.

Abstract: For identifying or localizing a serial data stream in a deserialized output provided at a plurality of n output ports (PORT1-PORT5), a pattern recognition is provided at each one of the plurality of n output ports (PORT1-PORT5) for recognizing a deserialized identifier pattern corresponding to an identifier pattern within the serial data stream and for detecting a phase of the deserialized identifier pattern in the deserialized output. The phase of the output of each respective port (PORT1-PORT5) is then shifted in correspondence with the detected phase of the deserialized identifier pattern.
