Electric Circuits I and II are important courses in electrical and electronic engineering, as well as electricity and magnetism. Electric Circuits II focuses on operating principles and the design of electric circuits in several application areas in electrical and electronic engineering, based on knowledge acquired in the course Electrical Circuits I. A filter is an electric circuit to create specific frequency characteristics by designing pole and zero locations. Creating the required frequency characteristics by designing pole and zero locations, the instructor discusses filter circuits with an LC ladder, and filter circuits with operating amplifiers and integrators. The instructor discusses transmission lines and frequency characteristics, impedance matching techniques for designing radio frequency circuits. In addition, the instructor discusses three phase AC circuits and basic switching power supply for the basis of power electronics.
The aim of this course is for students to gain an understanding of important electrical circuits in important application areas and to obtain the basic design skills for these electrical circuits.
At the end of this course, students will acquire the following abilities.
1) Can explain the basic structures and basic principles of analog filters as well as design them.
2) Can explain the basic principles of transmission lines, impedance matching, and a Smith chart, as well as design radio frequency circuits using them.
3) Can explain the three phase AC circuits.
4) Can explain the basic structures and basic principles of switching power supplies and design them.

|Intercultural skills||Communication skills||Specialist skills||Critical thinking skills||Practical and/or problem-solving skills|
Students must read the assigned part of the lecture notes uploaded to OCW-I before coming to the class. Students must make a report on the tasks shown in the previous class and submit it in class. Simulators will be used in class or for homework. MATLAB and LT spice should be installed on students’ PCs.
