Where I can find DSP/Analog recorded-Data

I know DSP people may have a better grasp on issue when come to recorded data for DSP.

The picture I am attaching is of a pulse oximeter sensor circuittry.

Where I can find data recordings from this circuit done on various patients.
There must be a place somewhere where I can take these data as text files, load them in Matlab or insert them in some DSP processor for analysis.

Thousands thanks, djalli

Can I at least know what would I expect as V0 min/max out of this circuit in absence of data? Thank you

First of all, using 1.6 Meg in series on the inverting OP input is obsolete and even harmfull. This technicue was used to symmetrize the voltage drop due high input bias currents in the ancient bi-polar input transistor pair. This resistor contributes both in high Jonson noise and noise due to the OP input current fluctuations. This resistor sould be avoided and J/FET input OP should be selected for the application.

Then what is the switch frequency for the LED's? The 2uF/1.6Meg HPF got 3.2 sec timeconstant (or 50 mHz cut-off). So far as I remember the switch frequency for the RED/IR LED in a pulse oximeter is in the order of hundreds of hertz, what means that the HPF cuttoff should be in order of tens of Hz, this way less 1/f preamplifier noise is propagated for the subsequent lock-in processor.
