Detect sudden jumps in current

[MichaelClerx]

See for example here:

Example strategies could be e.g.

• only look after cap artefact filtering
• treat each step individually (ignoring ramps)
• with some sliding window approach, using a "sensible" time scale e.g. dt=5ms, look for cases where
  • |mean(I[t, t+dt]) - mean(I[t+2dt, t+3dt])| > some sensible threshold, based on noise estimate, in words: a little segment before the jump differs from a little segment after the jump
  • but the slope of the before and after segment is the same (differs less than some threshold)

Or

• only look after cap artefact filtering
• treat each step individually
• fit the signal with multiple exponentials, or splines, or anything that wouldn't fit a little jump
• use the quality of fit as a jump detector
