Abstract
An electronic recognition circuit is described for use in bar code reader systems having postal and commercial applications. Such systems may be required to read codes which are of relatively poor print quality. The present circuit utilizes statistical auto-correlation techniques to reject extraneous ink dots and minor print voids commonly associated with such printing. Additionally, the circuit is skew tolerant and both position and velocity independent of the bar code being processed.
