Official abstract text for this publication.
According to an embodiment of the invention, an angle detection apparatus detects the angle of a rotation axis of a rotating device to generate a first signal and a second signal perpendicular to the first signal using the angle detection unit. The first AD conversion unit receives the first signal to perform an analog-to-digital conversion of the first signal. The second AD conversion unit receives the second signal to perform an analog-to-digital conversion of the second signal. The first offset correction unit receives a third signal output from the first AD conversion unit to perform an offset correction of the third signal when the third signal is outside a predetermined range. The second offset correction unit receives a fourth signal output from the second AD conversion unit to perform an offset correction of the fourth signal when the fourth signal is outside the predetermined range.
Opening claim text (preview).
What is claimed is: 1. An angle detection apparatus to detect an angle of a rotation axis of a rotating device to generate a first signal and a second signal perpendicular to the first signal using an angle detection unit, comprising: a first analog-to digital (AD) conversion unit to receive the first signal, the first analog-to-digital (AD) conversion unit to perform an analog-to-digital conversion of the first signal; a second analog-to digital (AD) conversion unit to receive…
