Abstract
A magnetic field sensor and associated method provide an output signal with first and second different pulses with first and second different pulse widths indicative of first and second different directions of rotation of a moving target. The magnetic field sensor also includes third pulses with an identifiable encoding to indicate when a signature region in the moving target proximate to the magnetic field sensor passes by the magnetic field sensor. The third pulses each comprise respective state transitions and each comprise respective pulse widths with respective fixed predetermined time durations.
