The course is focused to the native and evoked biosignals used in clinical medicine and current methods of capturing, processing, recording and evaluating in the time and frequency domains. For important biological signals, the students are introduced with their genesis, and nature and physiological characteristics of the signals required for construction of instruments. Students are introduced also with the physical and mathematical models. In laboratory exercises, students have the opportunity to capture their own biological signals and their subsequent processing in MATLAB.

Course outlines:

1. Introduction, biosignals, parameters
2. Voice and speech, F0, formants, characteristics of voice, speech disorders, phonetogram
3. Biological signal genesis, membrane potentials, neuron models
4. Signal of nerves and muscles, ENG, EMG signal processing, fatigue analysis
5. ECG systems ang signals, vector depolarization, the electrical cardiac axis
6. Description of ECG, basic images of ECG, VCG, filtering
7. Polycardiography - phonocardiography, pletysmogram. Wave detection, HRV.
8. Signals of the brain, EEG, rhythms, normal EEG, analysis artifacts
9. Abnormal EEG, graphoelements of paroxysmal activity, evoked potentials
10. Electrooculogram and electroretinogram
11. Polysomnography, classification of sleep stages
12. Auditory system, cochlear implant and the coding strategy
13. Pulmonary function, electrical activity of the stomach, elecrogastrogram
