Overview and Goals
The main goal of this course is
to introduce the basics of biomedical instrumentation:
- Applications: What do we want to diagnose?
- Physiology: Where are biological signals generated?
- Sensors: How can we record these signals?
- Signals: What properties do these signals
have?
- Signal processing and analysis: How can we
extract useful information from these signals?
This is a compulsory course for all students enrolled in the
biomedical engineering master's degree program. Most students will
take it during their first semester. Further info:
