Project Description

Course Overview

This online course discusses different types of electromagnetic interference (EMI) commonly found in RF and digital circuits together with practical techniques for minimising EMI effects. The module begins by introducing some basic EMI concepts and mitigation techniques before illustrating how these are applied in practice through a range of case studies.
