Abstract
This invention relates to modification and utilization of signals developed by automatic reading systems where a hand-held optical unit scans a data field or alpha-numeric characters, and more particularly, to operations which eliminate redundancy in signals produced by scanning a given data field in either direction. A higher first line accept rate is achieved.
