WebAug 13, 2013 · You only have rising edges in your current signal, so you could find the mean low signal and mean high signal and find where the data crosses this in both places. I've moved the thresholds by 0.001, but you'd need to set an arbitrary crossing threshold so that it isn't triggered by noise.

Using a waveform to trigger case structure but ignoring falling edge
