Abstract
A near field RF communicator has an IQ demodulator and a demodulator processor that identifies a transition between logical states on the basis of either: 1) a magnitude obtained by adding a first value representing a difference between positive and negative peaks in the in-phase modulation and a second value representing a difference between positive and negative peaks in the quadrature phase modulation; or 2) whether a combined value representing a rate of change in the in-phase modulation and in the quadrature phase modulation exceeds a threshold.
