Synopsis:

The native and evoked biosignals currently used in clinical practice are covered within this course. There are explained methods of their measurement, processing, recording and evaluating (especially in time and frequency domain). Explanation of more important biosignals is complemented by their origin, physiological bases, biosignal characteristics and physical and mathematical models. A few lectures is devoted to rheography and polygraphic methods.
