Abstract
This resolver digital converterincludes a band pass processing unit that is disposed between a conversion unit and a multiplication unit and passes only a signal of a predetermined band through processing performed with a period that is shorter than the sampling period of an analog-to-digital converter and corrects the gains of digital signals before being input to the multiplication unit by using gain correction values that are set based on the maximum value and the minimum value of each one of digital signals passing through the band pass processing unit.
