Abstract
An identification and/or sensor system includes a sensor that queries an identification and/or sensor configuration which contains resonators. A receiver receives an answer signal from the identification and/or sensor configuration. The receiver includes a phase-locked loop for converting a resonator decay signal into a signal of constant frequency and constant envelope curve.
