Planned learning activities and teaching methods

Teaching is based on lectures and laboratory experiments.

The course delivery will be based on theoretical lecturing, assignments and exercises solved in class. Exercises will be handed to students and their solutions shall be analysed at lecture periods. Additional tutorial time at the end of each lecture will be provided to students. Students are expected to demonstrate the necessary effort to become confident with the different concepts and topics of the course.

Lectures are supplemented with laboratory work carried out on the following topics: Basics of L and C Components and Oscilloscope Measurements, DC Behavior of RLC Circuits, Sinusoidal Steady State of an RC Circuit, Sinusoidal Steady State of an RL Circuit, Step Response of an RLC Circuit, Transfer Function and Frequency Response of a LPF and a HPF, Series Resonant Circuit, Parallel Resonant Circuit.
