It is shown how to use a 2n??1 length pseudorandom binary sequence to develop an absolute-type shaft encoder having any t resolution, where 2n??1??1coder rotating device has only two concentric code-track and 2n??1 reading heads. A sequential code-conversion method is used to translate the pseudorandom patterns into natural binary code.
