Prerequisites
Basic understanding of linear algebra, geometry, numerical analysis and algorithmic programming.

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
The course allows the students to acquire basic notions about the behavior of the electrical circuits, of the phenomenological models based on the electrical circuits and on the circuits for intelligent signal processing. Such contents will complete the set of notions acquired in the courses of physics, electromagnetism, calculus, geometry and programming and will enable the students to understand the fundamental equations that govern the linear and non-linear circuits, with and without memory, and some automated computation techniques instrumental in their analysis.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
The students will be able to analyze reasonably complex circuits by using method of decomposition of complex problems into simpler sub-problems and by using automated computation techniques as well as to understand the more general topics covered by the course. In addition, the students will be able to asserve the instruments acquired in the course, even in a synergy with other courses – such as data structures and data-processing algorithm, robotics, movement analysis – to their own creativity with the aim to deal with real-world and applied themes, either singularly or teamed up.
TRANSVERSAL SKILLS:
The development of didactic projects, that are carried on within small groups, will improve the students' ability to interact and communicate, the ability to learn and to draw conclusions, the degree of general independent judgment and the awareness about the real-world problems to be faced in information and automation engineering.

Program
The course is divided in two parts. The first part is devoted to the study of the fundamental elements, linear, time-invariant and memoryless and to the study of basic methods to analyze electrical circuits. The second part is devoted to the modeling of physical phenomena and engineering processes by means of non-linear dynamical circuits and to their solution by a computer. Part I: “Elementary bipoles, 2-port elements and linear, time-invariant, memoryless circuits“. Bipoles and generating functions (resistors, inductors, capacitor, indipenendent sources), 2-port nets (transformers, gyrator, nullor, Z and Y nets, driven sources). Circuit analysis based on mesh currents and on node potentials. Thevenin's and Norton's theorems. Part II: “Modeling of complex phenomena and processes by non-linear dynamical circuits and numerical solution techniques.“ Cases-study of non-linear, dynamical models and of their differential-type resolving systems (free and constrained) and numerical methods for their solution (Euler and Euler-Riemann methods). Elements of algorithmic programming in MATLAB/OCTAVE and examples of calculation of the dynamic response of non-linear dynamical systems.

Development of the examination
LEARNING EVALUATION METHODS
Learning evaluation methods: - a written test, to be completed in 90 minuts, about the solution of an electrical circuit; - a written test, to be completed in 30 minutes, consisting in the discussion of a theoretical topic. The “theory“ test may be replaced, upon request, by an applied project of algorithmic programming in MATLAB/OCTAVE. Both tests may be taken in different exam sessions and in any order.

LEARNING EVALUATION CRITERIA
In order to pass both tests, the candidate will need to show a good understanding of the proposed problems, to propose one or more correct solutions as well as to show a good ability to explain the proposed solutions correctly and by using an adequate technical language. The maximum score will be given to those candidates that will show a deep understanding of the course's contents.

LEARNING MEASUREMENT CRITERIA
Both tests will be graded by an integer in the range 0-30. The final evaluation will be calculated as the mean value of the two. In case of non-integer mean value, the rounding will be determined after a short interview with the candidate.

FINAL MARK ALLOCATION CRITERIA
The maximum score will be given to those candidates that will show a deep understanding of the course's contents and a very good ability to explain them. The “distinction mark“ will be given to those candidates who prove an outstanding ability.
