Mini-Project Objectives
1. exemplify engineering design/development process;
2. expose students to multidisciplinary/intercollegiate
aspects of engineering;
3. motivate students to continue their pursuit of an
engineering profession;
4. build an automatic blood pressure measurement devices while experiencing most aspects of the engineering design/development process.

CoE Advisory Board Meeting
Lab 2: Blood Pressure Signal Evaluation & Processing in Matlab
Classes 5 & 6
We provide signal files & Matlab programs
Issues: signal quality (noise and artifacts), demodulation, thresholding
12
CoE Advisory Board Meeting
Issues: calibration, robust heart beat pulse detection
