Learning and Teaching Methods
During the lectures students are instructed in a teacher-centered style. The tutorials are held in a student-centered style.
In addition to the individual methods of the students consolidated knowledge is aspired by repeated lessons in excercises and tutorials.
Additional project tasks for analysis and design of cicuits give the students the opportunity to apply their knowledge acquired during the lecture and the tutorials and to further deepen the understanding of the taught materials.
- lecture notes
- tutorial problems
- project tasks for analysis and design of amplifiers and oscillators

Description of exams and course work
In the written examination, students demonstrate by answering questions under time pressure and with limited helping material (10 pages or 5 sheets of self-generated documentation, mathematical equation book, non-programmable pocket calculator) the theoretical knowledge of components, amplifiers, and circuits. By solving analysis and design problems, they demononstrate the understanding of relevant physical effects and design principles.
During the semester, students get the opportunity to participate in voluntary project and design tasks, in which they can solve different analysis and design problems in more detail. These project tasks can be used to improve the final grade.
The final grade consists of the grade of the written exam (100%).
The overal grade for the project tasks will count with 20% of the final grade, if the average grade of the written exam (80%) and of the project task grade (20%) will lead to an improvement of the grade.
There is a possibility to take the exam in the following semester.
