how to calculate the ratio between the maximum and minimum peaks of the two waves using two looping to find the value of SPO2?

hello everyone,

i'm rai from indonesia

I have a final project about pulse oximetriy, I have some problems,

how to calculate the ratio between the maximum and minimum peaks of the two waves using two while loops to calculate SpO2 ?
My program image can be seen below predicament ?

Hi rai,

I would appreciate it as kind of respect for forum participants if you would clean up your VI before uploading it (or images of its block diagram)…

That being said:

- Your inner while loops each run exactly twice. Replace them with FOR loops!

- Lots of unneeded operations, mainly induced by ExpressVI usage. Is there a reason to convert to DDT and immediately convert back to 1D array?

- You already calculate some Min/Max values. Ratio is just a division of two values…
