The encoder including first and second detectors, each of which is arranged to produce a first alternating output signal as the track of encoding regions rotates about its axis past the detector. The detector identifying a usable pair of transitions and a rejectable pair of transitions and utilizing the pairs of transitions to produce a compensated position measurement for the rotary encoder.
