Abstract
Methods and apparatus for determining a mechanical angle of a target from sine and cosine signals generated by inductive sensing elements by applying harmonic compensation on the sine and cosine signals using possible mechanical angles and analyzing results of the applied harmonic compensation. One of the mechanical angles can be selected based on the results of the applied harmonic compensation. In embodiments, a cost function can be used to select the mechanical angle.
