Transfer function system for determining an identifier on a surface acoustic wave identification tag and method of operating the same |
摘要 |
A transfer function system for determining an identifier on a surface acoustic wave (SAW) identification tag and a method of operating the same. In one embodiment the system provides for (1) generating a radio frequency (RF) interrogation signal that causes a transducer located on a piezoelectric substrate to produce an initial acoustic pulse that reflects off of a plurality of reflectors arranged according to time and phase position on the substrate to yield response acoustic pulses, the transducer generating an RF response signal from the response acoustic pulses; and (2) determining the identifier by decoding the RF response signal in view of predefined time, phase and amplitude parameters.
