How can we break a repetitive data?

Let's say we apply current in a repetitive way:
I=-10 for 10 sec
I=0 for 180 sec
I=-5 for 30 sec
I=0 for 180 sec
and repeat it.
Then we get a voltage.
How can we separate this voltage figure into single pulses?
Each pulse is I=-10 followed by I=0.

Just do like this (example for the first range):
indexesToExtract = (t >= -10) & (t < 10);
thisPulse1 = completeVoltageSignal(indexesToExtract);
indexesToExtract = (t >= 0) & (t < 180);
thisPulse2 = completeVoltageSignal(indexesToExtract);
indexesToExtract = (t >= -5) & (t < 30);
thisPulse3 = completeVoltageSignal(indexesToExtract);
indexesToExtract = (t >= 0) & (t < 180);
thisPulse4 = completeVoltageSignal(indexesToExtract);
Repeat for any other time ranges.

Maybe try findchangepts().
Or you could try to get the moving mean with movmean() and then look for points above and below the mean.
If you need more help, attach some data so that we have something to work with.
