SIGNAL GENERATION DEVICE AND SIGNAL GENERATION METHOD

Abstract: one aspect of a signal generation device of the present invention includes n sensors that output n phase signals (n is a multiple of three) according to a rotation angle of a rotating body, and a signal processing unit that processes the n phase signal. the signal processing unit executes first processing of calculating a first n phase complex vector based on the n phase signals, second processing of transforming the first n phase complex vector into a first positive phase vector, third processing of calculating a second positive phase vector by normalizing, with a norm of the first positive phase vector, a real axis component and an imaginary axis component of the first positive phase vector obtained in the second processing, and fourth processing of inversely transforming the second positive phase vector obtained in the third processing into a second n phase complex vector.
