ABSTRACT:
A position sensor is provided with two target tracks which each comprise a plurality of magnetic and nonmagnetic segments. Each target track is associated with a magnetically sensitive device such as a Hall effect element. By appropriately positioning the locations of the pluralities of magnetic and nonmagnetic segments, output signals from the magnetically sensitive devices can be caused to generate preselected signal patterns. These signal patterns can be combined to synthesize a third output signal having a signal pattern of a desired characteristic which would otherwise be unobtainable through the use of a single target path configured with magnetic and nonmagnetic segments to directly generate the desired signal pattern.
