This course is organized according to flipped learning principles. The students are expected to complete independent studying and exercises before the contact sessions. The contact sessions ("lectures") are based on doing group exercises and discussions to deepen the knowledge from independent studies. Computer assignments are done independently, but help is available during the exercise sessions. Course grade is based on the overall points from the following components: 50 % of the points: - independent studies before the lectures - participation to contact sessions 50% of the points: - points from computer assignments - points from final exam |
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 and evaluate the basic properties and principles of biosignals and their measurements - Analyze examples and reasons for biosignal artefacts and missing data - Understand and evaluate different options for linear filtering of biosignals - Understand and evaluate the methods of spectral analysis and its applications in biosignal processing - Understand the statistical modelling of biosignals and classification problems - Understand the properties of performance estimations and the principles of hypothesis testing - Apply basic signal processing methods to real biosignals with MATLAB, visualize the results and analyze them critically Learning outcomes are described for grade 3.
