Teaching measurement uncertainty to undergraduate electronic instrumentation students

Measurement uncertainty is an important concept for electronic instrumentation students. This paper presents an easy way to explain this difficult concept that has been developed in the telecommunication engineering school of the Polytechnic University of Catalonia (Barcelona, Spain). The lesson development is based on a number of references from metrological associations that can be obtained from the internet. Two examples illustrate the process of evaluation and calculation of uncertainty in simple measurement situations.
