N2 - To get the sensor information from an individually addressed SAW sensor, the use of coded ID-tag type SAW sensors is combined with the tool of Wavelet transform, a kind of correlative signal processing. The function of SAW sensors (ID-tag type) is observed as a scaling of time and shape respectively. The time scaling factor is equal to the mechanical extension of the substrate of a sensor for temperature, etc. This scaling factor is evaluated by calculating the Wavelet transform. The fundamental concept, mathematical simulations, numerical estimations and finally an overview of the implemented SAW sensor system using the Wavelet transform processed within a SAW convolver are shown. Preliminary results are presented.
