Learning objectives

The course aims at providing basic knowledge and methods fior the analysis and synthesis of linear circuits in DC, AC and transient conditions. Part of the contents will be preparatory for later Electronics courses.

Prerequisites

Students must be familiar with the concepts and methods treated during the first year of the course (Mathematical analysis, Analytical geometry, Physics).

Course unit content

Analysis ans synthesis on linear electric circuits in direct current, alternating current, and transient operation. Energy analysis. Frequency analysis.

Full programme

Teaching methods

Classroom lectures and exercises solved by the instructor.

Assessment methods and criteria

1. Written exam with problems and theoretical questions. During the exam the student will have to demonstrate knowledge of circuit analysis and synthesis techniques in direct current, alternating current and transient operation, frequency analysis, energy analysis.

2. Optional oral exam for those students who successfully pass the written exam, mandatory for those who are slightly below 18/30. The oral exam can increase or decrease the written exam mark by up to 5/30.
