Adaptive Filtering for FSCW Signal-to-noise Ratio Enhancement of SAW Interrogation Units
A digital filter that improves the signal-to-noise ratio of the response of a FSCW (Frequency Stepped Continuous Wave) scheme is presented.An improvement in game of thrones jon snow poster signal-to-noise ratio represents an enhanced readout distance.This work considers this architecture as an interrogation unit for SAW tags with time and phase enc
