Hi everyone,
I have this signal where i need to detect only the peak right before the signal drops but I can't figure out a way to do it. Can anyone give me a hand?
Thank you so much!

Withoiut having the data to work with, one option could be the islocalmax function. Use 'FlatSelection','last' since the tops of those pulses could be considered ‘flat’. You will have to experiment.

One way you can do is finding the derivative of the signal.
For example: if the current derivative is 0 and both previous and next points are negative, then you found a peak before making a drop.
