Patent abstract
An RFID verifier is configured to vary a slope for a ramp-modulated interrogating signal to determine the slope at which an interrogated RFID tag no longer responds to the interrogating signal. In this fashion, the RFID verifier may obtain a measure of quality for the interrogated RFID tag with respect to the tag's ability to decode ramp-modulated signals.
