App note: Pulse Oximeter using dsPIC33

Here is a reference design of a pulse oximeter built around the dsPIC33 digital signal processor.

Pulse oximeter is a non-invasive medical device that monitors the oxygen saturation of a patient?s blood and heart rate. This application note demonstrates the implementation of a high-accuracy pulse oximeter using Microchip?s dsPIC® Digital Signal Controllers (DSCs) and analog devices.
