ABSTRACT:
A method and apparatus for determining the angular position of a point in rotational motion which includes a disk coupled to rotate with the rotating part. The disk includes a plurality of alternating teeth and spaces located about its periphery. At least one of the teeth has been removed to form an absolute or reference mark. A transducer is located adjacent to the disk to produce an electrical signal representative of the passage of teeth and spaces past the transducer. The electrical signal is processed to produce one or more output signals representative of the instantaneous angular position of the rotating part. Accurate results are produced even when large variations in instantaneous speed of the rotating part occur.
