Trying to find a function/sub VI/Somehting that will calculate an average minimum (sort of?)

[Bebo]

Hey guys,

I've got some data (noise) and I want to find what I would call an average minimum value for the noise as opposed to the single absolute minimum.  I'm wondering if you guys know of anything in LabVIEW I could use to do this.  I've attached a picture to explain what I mean.

Thanks,
Jeremy

If you're talking about averaging all the minimum points, I believe you should be able to do this by calculating the first and second derivatives of each point.
There is probably a VI for a point by point derivative or for an array derivative in the analysis palettes.

If this isn't what you want, you should explain what calculation is needed to obtain this.

There are many ways to do this. Perhaps you can simply plot histogram of the y-values and select the point where you have largest change.

Example histogram:
