Training objectives
- This is the first class to systematically tackle the study of electric phenomena and exhaustively examine all basic elements which compose an electrical or electronic circuit. The main objective of the class is to offer the fundaments for the study of electric and electronic circuits and is therefore a cornerstone for any other class in the domain of circuits or systems for the areas of electronics, automatic controls, telecommunications and computer engineering.
The main knowledge acquired ad the end of the class is:
- fundamental relationship of circuit theory;
- principal techniques for evaluating electrical variables (currents, voltages, and electric power) in circuits;
- model of all electrical one-port elements (resistor, capacitor, inductor, independent voltage and current sources) and of the main two-port elements (transformer, voltage/current controlled voltage/current sources);
- methods for analyzing linear a-dynamical (resistive) and dynamical (that is with reactive elements) circuits that operated in DC, transient and sinusoidal regimes.
The main skills (in terms of capabilities of applying the knowledge acquired) are:
- analyze the behavior of any linear circuit operating in DC, AC or transient conditions;
- identify design constraints that determine the value of the different parameters of simple electrical and electronic circuits. Prerequisites
- It is necessary to possess knowledge of the following topics from the basic Mathematics courses:
- matrices, vectors and elementary operations, linear systems and their solutions;
- solutions of linear differential equations of first and second order. Course programme
- The course includes 90 hours of teaching divided between theoretical lectures and exercises. More specifically, 60 hours are of lectures and 30 hours are of CAD exercises. The hours of lectures are divided as follows:
Electrical variables (5 hours)
Adynamical two-terminal elements (5 hours)
Circuit Theorems (7.5 hours)
Methods of Analysis (7.5 hours)
Dynamical two-terminal elements (5 hours)
First- and second-order circuits (10 hours)
AC circuits (10 hours)
AC Power Analysis (5 hours)
Two-port networks (5 hours) Didactic methods
- The course is organized as follows:
- pre-recorded lectures on all subjects of the course;
- classroom focus group related to the theoretical topics;
- classroom CAD (LTspice) exercises oriented to the solution of circuits. Learning assessment procedures
- Passing the final exam is the proof that knowledge and abilities outlined in the training objectives of the course have been achieved.
The final examination is a written test about theoretical arguments and solutions of circuits. In particular, one theory question and one exercise will be proposed to the student on all the topics of the course. Theory and exercise questions contribute equally to the final score. To pass the examination, it is necessary to reach a sufficient score, i.e., 18/30.
The test takes 90 minutes and it is not allowed consulting any textbook or document.
The examination list closes two days before the scheduled date.
The examination can be carried out in English. Reference texts
