Abstract

Processing a resolver signal by a microcontroller includes generating, by a carrier signal generator, a carrier signal for output to a resolver; receiving modulated carrier signals from a resolver via hardware that is external to the microcontroller; integrating, by an integrator, respective integrator input signals which are based on the modulated carrier signals, to generate respective envelope signals, wherein a start of an integration window of the integrator is set with respect to a start of the carrier signal; and determining an angular position sensed by the resolver based on the envelope signals.
