A system for discriminating between coded responses from multiple SAW
identification tags and a method of operating such system. In one
embodiment the system provides for a SAW tag reader subsystem that detects
coded responses from the tags to an interrogation pulse; and a coded
response analyzing subsystem, coupled to the SAW tag reader subsystem,
that employs signal processing techniques to separate portions of the
coded responses and generates possibilities for remaining portions of the
coded responses.
