Context: One approach to estimating BP from PPG signals consists of extracting features from PPG pulse waves, and then using these as inputs to BP estimation model. This tutorial covers the first of these steps: extracting features from PPG pulse waves.
Resource: You can read more about pulse wave analysis in Sections 3.2.2 and 3.2.3 of this book.
Explanation: See the figure above for an illustration of how Delta T is calculated.
Question: Can you implement any more pulse wave features (e.g. 'CT')?
