发明名称 APPARATUS FOR PROVIDING CONVERSION BETWEEN ANALOG AND DIGITAL VALUES
摘要 This invention relates to an encoder or converter which provides a conversion between analog and digital values of a functional relationship between two independent variables. For example, the invention provides a conversion between analog and digital values of a function R sin theta . The conversion is provided in accordance with the synchronous movement along two coordinate axes of a plurality of encoded patterns relative to sensors associated with the patterns.
