Learning Outcomes

This course provides the basics of applying signal processing methods on biosignals of physiological or behavioural origin. Student is assumed to have basic signal processing method knowledge and basic skills for using Matlab prior the course. After this course, the student can: - describe the common properties of biosignals, and describe basic challenges in processing and analyzing them. - explain the principles of filtering and spectral analysis and select suitable methods for applications in health and biology. - analyze common methods of statistical modeling of biomedical or behavioral signal data and explain the assumptions of the models. - assess the performance of a developed biosignal processing or analysis method. - apply signal processing methods to biological signals including EEG and ECG. - implement such methods to process biological signals.
