Hello everyone, I have some very noisy signals and they have several peaks. I'm looking at a specific region of my signal to find the peak in that region but soemtimes that peak may be minimum and sometimes maximum. How can I get the min or max without specifying if it's min or max cause it changes for each signal.

So I came up with an idea which is find the peaks in that specific region, then find the min and max and then compare the absolute values. whichever has a bigger absolute value, that's gonna be my peak :). But any better suggestions?
