Course detail

Biological Signal Analysis

FEKT-AABSAcad. year: 2010/2011

The subject is focused on native and evoked biological signals (biosignals) in man, It deals with the types and characteristics of electric, magnetic, sonic and mechanical signals generated by the individual systems in human organism and on the methods of their representation, including polygraphic methods. It emphasises the use of general and specific methods for pre-processing, analysis and interpretation of biosignals.
