Question about deconvolution of signals (digital signal processing)

AI Thread Summary
The discussion centers on the challenge of identifying a specific peak in a set of discrete data that has undergone Gaussian smoothing. The user initially struggled with the peak detection using MATLAB's findpeaks() function due to interference from an adjacent Gaussian. They sought advice on obtaining the x value of the desired peak around x=35. Ultimately, the user resolved the issue by utilizing the local minima of the derivative, identifying an inflection point near the target value. This highlights a practical approach to peak detection in smoothed data.

I have a set of discrete data that I have performed multiple Gaussian smoothing filters on to act as a low-pass filter. What I have come up with is something like this:

I'm using findpeaks() in matlab, and a peak that I want is being taken over by the adjacent Gaussian. The one I'm trying to get is around x=35. Does anyone know of a method where I can get the x value of that point? Thanks!

Nevermind, I figured it out. I ended up using the local mins of the derivative.
 
FWIW, I was thinking that there is an inflection point around 35.
