Abstract
An angle encoder has first and second components rotatable with respect to each other, and an encoder pattern having codewords for indicating the angle between the first and second components. The encoder pattern has a set of base encoder channels coded with a conventional Gray code, and a set of Booster channels for improving the resolution of angle measurement.
