Knowledge of the basic laws governing electrical circuits. Knowledge of analysis method for electrical circuits. Knowledge of the properties of the responses of linear time-invariant circuits. Ability to compute and explain the responses of electrical circuits. Ability to relate the responses of circuit models to the behavior of real systems. Ability to use a modern computer program for Computer-aided Circuit Analysis (SPICE).

Physics: power and energy, basic electromagnetics. Mathematics: linear algebra and matrix analysis, first-order linear differential equations, algebra of complex numbers, partial fraction decomposition of rational functions.

The course is structured in a “core” part (8 credits) and an “advanced/applications” part (2 credits). The “core” part is common to all the students attending the course. The “advanced/applications” part is only for students enrolled in the Electronic and Communications Engineering and Physics Engineering (not required for Computer Engineering students). 1. Core part (8 credits) Kirchhoff equations, nodal analysis, general properties of linear resistive circuits, linear resistive 2-port elements, linear dynamic circuits, Laplace analysis, ac circuits and frequency response 2. Advanced/Applications part (2 credits) Automated circuit analysis (SPICE), Resonant circuits, LTI 2-port elements, Reciprocity, Nonlinear resistive circuits, Fundamentals of switched-mode circuits, Circuit models for multi-physics problems.

This course is delivered in remote mode, via virtual classrooms with the support of e-learning tools. It is divided in eight chapters, the first seven ones covering the core of the course (8 credits), whereas the last one covering the advanced topics and applications (2 credits). Every chapter of the course is composed of a set of learning units, including video clips, online explanations, as well as problems and questions assigned to students in real time and as homework. The learning of the students is monitored thru the assignments and the content of the learning units is adapted accordingly.

Exam: Optional oral exam; Paper-based written test with video surveillance of the teaching staff; Computer-based written test using the PoliTo platform;

The knowledge and the abilities gained in this course will be verified during the final examination, which is structured in a written test via the EXAMS platform, followed by a validation session, possibly including an oral test, carried out in a virtual classroom. The written test has a “closed book” format (no books and notes, calculators provided by the proctoring system), it is composed of five elemental multiple choice questions (duration 30min, up to 24 points) and circuit analysis problems with open questions (duration 1hour, up to 6 points). The written test is passed iff the grade of the multiple choice questions is at least 18/30. The oral test will be based on two questions about any theoretical or practical topic presented in the course. The oral test can be requested by students with a mark of the written part larger than 20/30 or can be imposed by the examination board in case of difficulties in assessing the written test of the candidate. The basis for the final mark is provided by the score of the written test, which can be increased (or decreased) based on the possible oral test. The grading criteria take into account: • the correctness of the answer provided to the written problems and oral questions • the clarity and the technical wording of the answers given by the candidate • the autonomy and promptness of the student in providing the answers

Exam: Written test; Optional oral exam; Paper-based written test with video surveillance of the teaching staff; Computer-based written test using the PoliTo platform;

In case it is allowed, the written and the oral test may be taken in real classrooms, in the same way they are taken via the EXAMS platform and virtual classrooms.
