2. Measurement principles used in bioelectrical, hemodynamic and respiratory monitoring.   Benefits and drawbacks of different measurement principles.   
3. Structures of the circuits used in biomedical measurement systems.  Operation principle of phase-locked measurement.   
4. Electrical safety requirements and design of electrically safe medical devices. .   Requirements of various types and classes of electrical medical devices.    
5. Sources of noise and interference. Elimination or minimizing noise coupling in medical electronic systems.  Protection of electronic devices against transient voltages and electromagnetic interference.   

Instructions for students on how to achieve the learning outcomes

The final grade of the course is determined based on the assessment of all part of the course. The weighting factor of each part is given at the beginning of the course. Grades 1-2: Learning outcomes have been achieved. Satisfactory command in core content of the course. Grades 3-4: Some learning outcomes have been exceeded qualitatively or quantitatively. Good command in core content and complementary knowledge of the course. Good or very good marks from all parts of the course. Grade 5: Most of the learning outcomes have been exceeded. Deep command in the whole content of the course. Almost maximum performance in all parts of the course.

Assessment scale:

Numerical evaluation scale (0-5)

Partial passing:

Completion parts must belong to the same implementation
