hello, hope every one is doing great, i created a pulse oximeter sensor, to get the right information from the sensor, i have to make a filter, from my resources, i found that the cut frequency is between the 0.7Hz and 2.34Hz, but on mu oscilloscope, I found it between 0.7Hz and 15Hz
My project is to create a pulse oximeter to calculate the oxygen saturation, heart rate
my question is
where is the right frequency area ?
thank you for helping me in advance
