Find jumps in Signal take constant area and split signal to different mat files

3 Ansichten (letzte 30 Tage)
Hey guys,
I have following Signal:
I need to split this signal into different mat files.
My problem i have the noise and the transient behaviour.
I need to save the constant "areas" into the different mat files.
In this case I have 7 to 8.
Thanks in advance.

Yes. This is the Y-Axis.
Just Build a vector
t = 1:1:length(signal)
should be the same effect.

Maby an easier question.
How do I get the first value when it reached the next jump? I mean if it gets constant (green lines) that would be the best.2019-03-05_11-42-04_1.png

I tried to smooth data. Then get every 600th point to compare with noise value and filter.
Then comparing points to find stable areas.
Hard to pick parameters for data (smoothing and filter). Maybe with user interaction it will be a little bit easier to draw those areas. See attached script

Thank you very much for your effort.
I am going to test it later.
But can I adpat this code 1:1 to following data?

Or do I have to change smth. in the code?

Hard to say. It depends on data, try to change smooth coefficient and filter point if needed.
