  • Abstract
    A new pseudorandom, two-track encoding procedure for absolute-type shaft encoders with any number of disc sectors has been developed. For n-bit resolution the new method requires only n + m reading heads, where 2m-1 < n¿2m. This is notably better than the 2n¿1 reading heads required by an earlier version.
