Hello people,
I am developing a VI for Heart Rate Variability Analysis. I have plotted a Power spectrum Density plot. I however am not not able to select frequency ranges by sliding bars on the waveform graph. I would like to select a part of the displayed signal and process it (calculate power). It seems simple yet I cant get it. I think ti is to do with property node, but there are so many, I cannot figure out the right one.
Solution please.
Thank You
Jas

What I really want to do is calculate power for a range of frequencies in FFT.
I have plotted the PSD and extracted the frequency ranges from the PSD array by specifying index values in teh array. Does this sound reasonable???
Also I now need to calulcate power for this range of frequency. How can I do that?
