Abstract
Systems and techniques for eliminating or compensating for noise affecting a bar code scanner. A scanner is operated in a learning mode under conditions designed to insure that a scan signal will take on predictable characteristics and noise affecting the scan signal will be easily detectable. During the learning mode, information relating to noise affecting the scan signal and the conditions under which the noise occurs is stored. During normal operation of the scanner, the stored noise information is used in controlling operation of the scanner so as to eliminate or compensate for noise under conditions in which noise has been shown to be susceptible to occur.
