Statistical Methods in the Design and Development of Electronic Systems

A study is made of certain factors affecting tolerance assignment in the production and operational stages of an electronic system. The procedure adopted is first to review very briefly some of the fundamentals of the statistical control of quality and the assignment of valid, economical production tolerances, and second to describe how the principles may be applied in the setting of some operational tolerances for an electronic system. The advantages to design and development derived from a knowledge of how tolerances, both productional and operational, are assigned, and how they combine statistically, are discussed.
