Abstract
A signal converterincludes, for at least two-phase signals detected by a resolver excited by a carrier signal having a carrier frequency fc, a first phase shifterthat shifts a phase of a first phase signal of the resolver with a pole at a frequency flower than the carrier frequency fc, a second phase shifterthat shifts a phase of a second phase signal of the resolver with a pole at a frequency fhigher than the carrier frequency fc, and a synthesizerthat combines the phase-shifted first phase signal with the phase-shifted second phase signal.
