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, ODE.
Teaching Methods
The lectures are held with the help of blackboard and slide based presentations. The slides are made available to students. Numerical exercises and tutorials are organized too.
Assessment Methods
The final examination consists of a written test and a voluntary interview. The written test consists of two numerical exercises.
