Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.


1. Can describe the main features of the physiological, physical and chemical background to the most common bioelectrical phenomena.

2. Can model and analyze these phenomena using a computer.

3. Can describe the structure and operating principle of some of the most common diagnostic and therapeutic equipment.

4. Can identify interference factors and their coupling mechanisms and explain solutions for shielding against the effects of interference.

Assessment Methods and Criteria
  • Valid 01.08.2020-31.07.2022:

    Lectures, exercises and group work.

  • Applies in this implementation:

    Grading is based on exercise problems and group work. There is no exam.

    Exercise problems: 60 p (five rounds, 12 p / round)

    Group work: 35 + 5 p

    • 35 p: presentation and report
      The points awarded depend on the grade of the report:
      Excellent: 32–35 p
      Very good: 28–31 p
      Good: 24–27 p
      Very satisfactory: 20 - 23 p
      Satisfactory 16 - 19 p
    • 5p: Evaluate at least two reports by other groups (mandatory)

    Total: 100 p

    Bonus points:

    • Evaluate additional group work reports (1 p / report past the first two)
    • Course feedback (1 p)

    The points are converted to final grades according to the following table:

    Excellent (5):         82.00 to 100.00 points
    Very good (4): 74.00 to 81.99...
    Good (3): 66.00 to 73.99...
    Very satisfactory (2): 58.00 to 65.99...
    Satisfactory (1): 50.00 to 57.99...

    Explanation for the point grade limits:

    • For passing the course (1), you need to get one half of the maximum points (50 p).
    • A grade of Excellent (5) can be obtained, for instance, by getting an Excellent grade from the exercises (> 48 p), a Very Good grade from the group work (> 29 p), and evaluation of two group work reports (5 p). 48 p + 29 p + 5 p = 82 p.

  • Valid 01.08.2020-31.07.2022:
