Learning outcomes:
After completing this course students will have acquired:
- the theoretical fundamentals of metrology, measurement statistics, stochastic processes and error propagation;
- the theoretical knowledge necessary to analyse rival measurement methods and instruments and to create and implement new measurement ideas and techniques;
- specialist knowledge, expertise and practical skills in effective and spectral measurement technologies using both absolute and ‘level’ units. The course focuses on the analytical, computational and practical approaches to handling faulty measured quantities, and inner, outer, passive, active and parasitic disturbances. All measurement and computational procedures must be carried out analytically to any required level of precision or must be estimated and checked by calculation to a degree of precision acceptable for the specified practical application.
