Method and apparatus for correcting resolver errors

Abstract From the Canadian patent

Method and Apparatus for Correcting, Resolver Errors Abstract of the Disclosure, A synchro-to-digital converter circuit is disclosed which includes memories that store digitized representations of the waveforms produced by the resolver. By matching these digitized waveforms to the specific resolver with which the circuit is to be employed, errors produced by the resolver are compensated. Two embodiments of the synchro-to-converter circuit are disclosed as well as a circuit for creating and storing the matched waveforms.
