ABSTRACT
This chapter addresses several further issues of sensing instrumentation that affect the performance of an engineering system. Particularly, bandwidth considerations, data sampling, error and its representation, combination, and propagation are studied in some detail. It address various interpretations of bandwidth. The chapter focuses on instrument bandwidth and control bandwidth. Within that focus, bandwidth directly concerns some form of largest possible operating “speed” such as the speed of response of a dynamic system and the speed of control. It deals with pertinent considerations of representation, classification, combination, and propagation of error and sensitivity analysis. In any multicomponent system, the overall error depends on the component error. Component error degrades the performance of an engineering system. Bandwidth plays an important role in specifying and characterizing the components of an engineering system. In particular, useful frequency range, operating bandwidth, and control bandwidth are important considerations.
