Min/Max for computing damping

Here are two ways to do it without using a loop.  One uses In Range & Coerce to get a boolean array of peaks within the desired range. The other uses Threshold 1D Array on a reversed array.

Note: If you choose one of these methods, you will need to extract the same subset of the Locations array.

Well, it wasn't for a lack of trying...I looked at this for 10 hours today...I guess I need more sleep.Thank you Lynn.

Lynn, why would I need the location if I have the index(amplitude)? My time values don't really matter to me.

[glskinner84]

All I'm really looking for is the index in which the decay begins...I get then add 5 to this and get my 6th amplitude value in the decay.

If you were to fit the data to an exponential as I mentioned earlier, then you would need both amplitudes and locations. For your ratio method you do not need the locations.

 I think I will try both to get a comparison. The locations tie into the 'X' input on the exponential fit.vi, correct? 

[johnsold]

Yes.
