Abstract
In an angle detection method with a resolver, the method being for detecting a rotational angle of a rotator by synchronously detecting a first signal and a second signal that are two phase sine wave modulation signals obtained from a one phase excitation/two phase output resolver, the method includes: a first signal detection process which detects a signal in the order of the first signal and the second signal; and a second signal detection process which detects a signal in the order of the second signal and the first signal.
