Hello,
I read signals from a measurement file which have 1 to 4 breaks (where the signal falls the most, see example) and have to detect these positions (temperatures). The algorithm is the following: make the first derivative and take the absolute values and search the maximums.

The signals can be quite noisy so I have to filter them first. I tried all the curve fittings but with no success, it's even harder to find the peaks afterwards. What would be the best way to fit these signals (as already said, they can have up to 4 breaks, the example has only 2)
I attached a VI with the data in it.
Regards,
Rico
