detect start / end of signal peak in time stamp - data series
I have a data file contains timestamps - data signals.
I was trying to detect the peak of the signals as well as the start and end of the peaks.
Referred to this post, I could detect the peak with no issue.
The questions is how to robustly detect the start / end of the peak signals?
How do I detect the start of continuous rising, or the end of continuous decreasing trend of the signals?
I am very new to digital signal processing. Any advise are welcome.
Solution
I followed this matlab findpeaks link to define the start and end of peaks.
It describes the definition of prominence (thus the width) of peaks.
