A COMPARISON OF TWO LOGIC SYMBOL CODING TECHNIQUES IN A SIMULATED DIGITAL DEVICE MAINTENANCE ENVIRONMENT
Abstract
This study was designed to evaluate which of two techniques is better for encoding the logic symbols in detailed logic diagrams to convey information about digital circuits. One technique employed shape encoding to differentiate basic logic functions; the other used alphabetic identifiers. The findings showed that using shape encoded symbols in simulated detailed logic diagrams resulted in a significant reduction in the time required to solve maintenance type problems. It is concluded that shape encoding is the better of the two techniques, for use in operational situations, if time-saving is of concern. Based upon observations made during the design and conduct of this study, two sets of recommendations are made. (Author)
