Analysis of Photopletismographic Signals at Different Sampling Rate
Photoplethysmography is a convenient and easy to use method for obtaining information about the human cardiovascular system. It is based on the use of the property of tissues to absorb light passing through or reflected from them. The received analog signal when using this method is converted into digital for further processing. The article presents an experimental system for recording photoplethysmographic signals. The data obtained during the digitization of the analog signal with different sampling rates are shown.
