The main objective of the course is to introduce students to the basic laws governing lumped electrical circuits, giving suitable and general methods for their analysis. In particular, the course provides fundamental tools to analyze dynamic circuits in the time and in the frequency domain. An introduction to automated circuit analysis via computer-based simulation is also provided. The theory is complemented by several practical classes.

The course is structured in two parts: a "basic" part (2 credits) and a "core" part (5 credits). 1. Basic part (2 credits) Lumped circuits; voltage, current and power. Reference directions. Kirchhoff's laws. Tellegen's theorem. Basic circuit elements. Series and Parallel connection of the resistive one-port elements. Current and Voltage division rule. Millman's theorem. Maximum power transfer. Nodal Analysis. 2. Core part (5 credits) 2.a. General resistive circuits (1.5 credits). Dependent sources, ideal operational amplifier.

Network functions: impedance, admittance and transfer functions. Bode plots. The course is organized into lectures and practical classes. Practical classes (approximately 30% of each credit) are aimed at applying the general circuit analysis methods presented during the lectures. During practical classis, active participation of the students is required. A few hours are dedicated to a basic introduction to computer-based circuit simulation programs (SPICE).

Modalit� di esame: Prova scritta (in aula);
Exam: Written test;
... The knowledge and the abilities gained in this course will be verified during the final examination, which is structured in a written test, followed by an optional oral test. The written part has a duration of 90min (1h and 30min). The test includes three elementary multiple-choice questions each of which has only one correct answer (duration 15min up to 6 points) and circuit analysis problems with open questions (duration 75min, up to 24 points). A correct answer to a multiple-choice question gives 2 points. An incorrect answer gives a penalty of 2 points. There is no penalty for blanks. The exam is graded iff the candidate gets at least 2 points from the multiple-choice questions. During the text, it is possible to use a scientific calculator; no texts, books and notes are admitted. The written test is passed with at least 18/30. The oral test can be requested by students with a mark of the written part larger than 24/30 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 (optional). Important: A single final mark is registered for the Electromagnetics and Circuits course (12 CFU). The grade will be determined by a weighted average of the grade obtained in both modules (i.e., Electromagnetics (5 CFU) and Circuit Theory (7 CFU)). The examination of the two modules must be taken in the same academic year.
Gli studenti e le studentesse con disabilit� o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unit� Special Needs, al fine di permettere al/la docente la declinazione pi� idonea in riferimento alla specifica tipologia di esame.
Exam: Written test;
The knowledge and the abilities gained in this course will be verified during the final examination, which is structured in a written test. The written test has a duration of 90min and consists of two parts: - PART A: six (6) multiple-choice questions each of which has only one correct answer (up to 18 points) - PART B: two (2) circuit analysis problems with open questions (up to 12 points). For PART A, an incorrect answer to a multiple-choice question gives a penalty of 1/3 of the points that would be assigned to a correct answer. There is no penalty for blanks. PART B is graded iff the candidate gets at least 6 points from PART A (i.e., the multiple-choice questions). During the text, it is possible to use a scientific calculator; no texts, books and notes are admitted. The test for the "Circuit Theory" module is passed with at least 18/30 points. Important: A single final mark is registered for the Electromagnetics and Circuits course (12 CFU). The grade will be determined by a weighted average of the grade obtained in each module (i.e., Electromagnetics (5 CFU) and Circuit Theory (7 CFU)). The examination of the two modules must be taken in the same academic year.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
