Abstract :
The round-off and truncation errors of a digital-analog (hybrid) servo system are studied in terms of the least upper bound and second moment, or variance. The study was applied to the azimuth function of a guided missile launcher system and a digital controller designed for the launcher system. The techniques employed can be generalized and applied to other analog-digital or digital systems.
