Find baseline and sudden signal changes (as well as duration until return to baseline) for noisy data

조회 수: 7 (최근 30일)
I'm struggling with some data I extracted and hoping for some help on how to best deal with it. I have attached an example
The presumed baseline is marked in red. I have multiple consecutive events indicated by a sudden change in baseline and then becoming weaker over time before changing back to basline. I would need the length of such an event. How can I best determine the baseline and relaibly measure the lengths of these events. Hope someone can give me some directions

You may find the Signal Processing Onramp very helpful. Chs 3 and 6 look directly applicable here, but perhaps some of the others will iterest you as well.
