Abstract
A system and method for determining information related to a rotation of a shaft. The method includes receiving a signal associated with a plurality of targets and gaps passing by a sensor. The targets and gaps are positioned around a circumference of a wheel that is fixed for rotation with the shaft. The method includes forming a sensed target-and-gap sequence based on the signal, wherein the sensed target-and-gap sequence represents a subset of the targets and gaps. The method further includes comparing the sensed target-and-gap sequence to a set of known target-and-gap sequences stored in memory. Each known target-and-gap sequence is associated with a respective known circumferential portion of the wheel. The method also includes determining which respective, known target-and-gap sequence is identical to the sensed target-and-gap sequence.
