Abstract
A position transducer has a moving modulating portion that can move to various positions through rotation, for example. The position transducer provides at least one analog signal that varies periodically with the moving position of the modulating portion, where the movement of the modulating portion has a period. The analog signal is provided to a converter that converts the analog signal into digital information which is applied to a computing arrangement to provide information as to the position of the modulating portion by using at least one transformation including stored information as to deviations of the periodic variation of the analog signal relative to a sinusoidal shape having a constant amplitude for all periods of movement of the modulating portion.
