Abstract:
A system and method for reducing noise in resolver-to-digital converters (RDC) using a cascaded tracking loop filter. In some embodiments, one or more tracking loop filters may be implemented in a cascade to attenuate carrier harmonic frequencies in the digitized output of an RDC. Where a plurality of tracking loop filters are implemented, the output of one tracking loop filter may be input into a successive tracking loop filter.
