A New Encoding Scheme for an Absolute Digital Encoder in Units of Degrees
Chang-Kyung Sung, Uno Raudkivi · IEEE Transactions on Industrial Electronics and Control Instrumentation · 1980
Cyclic codes are often used in encoders to avoid possible erroneous readings. Special attention must be paid to codes where changes in certain digits are ``irregular.'' An angular encoder that provides readings in degrees is such an example. A new cyclic encoding scheme for a degree-reading encoder is proposed in this paper. While keeping the encoding simple and efficient, the method considerably reduces the external decoding circuit requirements.
