Abstract
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¿1<t<2n¿1. The shaft encoder 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.
