Objectives
This course introduces the fundamental concepts of the Electromagnetic Compatibility. The goal is to provide knowledge on the conducted and radiated emissions and immunity, the electromagnetic coupling, the analysis of the most commonly used models to the evaluation of the disturbance levels, the introduction to the normative and to the methods and instrumentation for the evaluation of the electromagnetic compatibility of electronic devices in pre-compliance and compliance to the technical standards. After the course, the students are expected to be able to use simple models for the electromagnetic compatibility analysis, to understand the procedures for EMC verification and certification according to the existing normative, and to plan and execute the principle EMC measurements. Specific knowledge will be given on the main solutions for an EMC-aware design, addressed to the removal and/or mitigation of the main EMC problems.
