I have a waveform in time and velocity and I want calculate the amplitude using peak to peak amplitude concept. How to do it?

Do you just want the min to max over the entire signal
amplitude = max(waveform(:)) - min(waveform(:));
or do you want the amplitude in a moving window? If in a moving window, what should the window width be?

I'm not sure about the window width, but I need calculate the peak to peak amplitude in every single wave (every positive and negative peak). Is it possible?
