Knowledge of electrical quantities and units involved in the study of circuits; knowledge of linear one-port systems and their energy properties; knowledge of circuit laws and their numerical implementation; ability to solve simple circuit problems in DC, low and high frequency, in resonance or transient conditions.
Course Prerequisites
Linear algebra, complex numbers, derivatives and integrals.
Teaching Methods
Lectures (hours/year in lecture theatre): 46 Practical class (hours/year in lecture theatre): 36 Practicals / Workshops (hours/year in lecture theatre): 0
Assessment Methods
The final examination consists of two written tests. The first test is composed of two numerical exercises. The second test is based on one exercise, where the candidate is supposed to answer to a few fundamental questions in a numerical form.
