Abstract
An aspect of a signal generation device of the present invention includes a processing device that calculates angle information indicating a mechanical angle of a rotary shaft, and generates a first signal in which a waveform of one electrical angle cycle appears N times (N is an integer of one or more) in one mechanical angle cycle, and a second signal different in phase by 90 degrees in electrical angle from the first signal, based on a calculation result of the angle information.
