I am working on a project based on Photoplethysmography for measuring blood pressure, heart rate, etc. by detecting blood volume changes under the skin tissue using a VISHAY TCRT1000 optocoupler. However, I wanted to process the signal on my PC using MATLAB. For this purpose, I have bought a USB Data Acquisition Card for feeding the signal to my PC. Can someone please suggest how can I use this to feed the signals to MATLAB? I have to deal with analog signals.
