Lukyanov V. D., Ozhiganov A. A. Code scales for movement converters with high informational reliability, based on recurrent sequences


This paper considers one-track recursive code scales construction principles, which were denoted as pseudorandom and compositional code scales according to informational track pattern used for their synthesis. These scales may be used as coded elements of movement converters. Recursive code scales achieve better size and weight characteristics in comparison with traditional code scales by using only one informational code track. Moreover, it allows to generate codes with correction and (or) detection of reading errors only by introducing extra code sensors without introducing additional code scales.

Keywords: code scale, code sensor, recurrent sequences.
