Model of a Self-Correcting Digital Angle Converter Based on a Pseudorandom Code Scale

An approach to restoring information lost during the reading process in a digital angle converter using pseudorandom code scales is presented. An algorithm is proposed that uses linear recurrent sequences generated by shift registers with linear feedback, which provides error correction during dynamic reading of information from the code scale. A distinctive feature of the approach is the use of an odd number of reading windows, which significantly increases the information reliability of the system.
