EEC 604 Advanced Instrumentation Resit 2022

About this paper

EEC 604: Second semester resit examination (June 2022) for EEC604 (Advanced Instrumentation) at the University of Buea College of Technology, set by Dr Feudjio. Question I covers the general measurement-chain model, the four main types of measurement error, dynamic characteristics of instruments, and a strain-gauge derivation of the resistance change under tension and the gauge factor in terms of Poisson's ratio. Question II covers error propagation: evaluating an algebraic expression with uncertain inputs, and a resistor-network error-propagation problem.
