Obiettivi

Course objectives: Electromagnetic Compatibility is the discipline that studies electromagnetic interactions between electrical and electronic devices and systems. The fundamental objectives are aimed at identifying and analyzing the sources of disturbance that characterize the electromagnetic environment in which the various devices are immersed, in determining the possible couplings and the interferences produced, in identifying the protective devices, in defining the constraints of a project. The investigation tools are based on the theory of electromagnetic fields and electrical circuits. This knowledge is of fundamental interest to the electronic engineer.

Knowledge and understanding: upon passing the exam - Starting from the principle that an electrical or electronic apparatus is compatible with one's work environment if it can function satisfactorily without generating or being subject to intolerable disturbances that impair its functioning student must have acquired the primary basic knowledge relating to the concepts of disturbance, the relevant sources, the mechanisms that determine it, and finally the techniques and means of protection to be used on the disturbance source, on the coupling path or on the perturbed apparatus to mitigate the flu effects.

From all these knowledge, the main skills acquired by the student, in terms of ability to apply the knowledge acquired and to adopt the appropriate approach with independent judgment, will consist in the ability to identify and classify the type of disturbance, and to select the most appropriate set of techniques to solve a specific Electromagnetic Compatibility problem.

The exam consists of an oral test accompanied by the discussion of an essay.

The essay aims to assess the student's ability to apply the knowledge acquired during the course to problem-solving

The oral exam aims to ascertain the level of knowledge and understanding of the course contents, assessing autonomy of judgment, learning ability and communication skills. The oral test consists of the discussion of the written test, in questions and/or exercises on the course content.

The final grade of the exams is determined, taking into account both the paper and the oral exam. The evaluation grid adopted is defined as follows: If the student demonstrates a basic knowledge of the main topics, a basic knowledge of technical language, a sufficient interpretative ability, a sufficient ability to apply the basic knowledge acquired, the score achieved will be between 18 and 19; If the student demonstrates an adequate knowledge of the topics but limited mastery of them, a satisfactory property of language, a correct interpretative ability, a more than sufficient ability to independently apply the knowledge to solve the proposed problems, the score achieved will be between 20 and 23 ; If the student demonstrates a knowledge of the topics with a good degree of command, a good property of language, a correct and safe interpretative ability, a good ability to apply most of the knowledge correctly to solve the proposed problems, the score obtained will be between 24 and 27; If the student demonstrates a complete and in-depth knowledge of the topics, an excellent language property, a complete and effective interpretative ability and will be able to independently apply the knowledge to solve the proposed problems, the score obtained will be between 28 and 30; The score of 30 and honors will be achieved by the student capable of demonstrating a complete, in-depth and critical knowledge of the topics, an excellent language property, a complete and original interpretative ability and a full ability to independently apply the knowledge to solve the proposed problems;
