Abstract
A programmable, electronic, angular position indicator, based upon engineering units, estimates the angular displacement of a rotating rotor. The angular position indicator is programmed with the particular arrangement of teeth (or other markings) on the rotor. Intermediate angular displacements are interpolated between a limited number of positive angular displacement indications. Offsets, due to acceleration or deceleration of the rotor, are corrected at each positive angular displacement indication without skipping the output of each interpolated angular displacement. Angular displacement is determined in standard engineering units.
