Abstract
A resolver includes an excitation coil for receiving an excitation signal formed by amplitude modulation of a high-frequency signal and a detection coil for outputting a detection signal. The resolver is arranged to detect a change in position of a rotor provided with the excitation coil or the detection coil based on the detection signal varying with the change in position of the rotor. The high-frequency signal is a digitized signal generated from a reference clock.
