The rotation angle detection device includes a correction value calculation unit configured to calculate a correction value of the rotation angle; an angle output unit configured to output an angle output signal indicative of the rotation angle of the magnetic field generation source, based on a magnetic field detection signal to be output from the magnetic field detection device and the correction value; and a filter unit capable of selecting a first filter characteristic, which is to be used for outputting the angle output signal, and a second filter characteristic, which is to be used for calculating the correction value and is different from the first filter characteristic."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotation angle detection device, rotation angle detection method and program","description":"Provided is a rotation angle detection device configured to detect a rotation angle of a magnetic field generation source, based on a magnetic field in at least two directions detected by a magnetic f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11243065","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
