What I want to be able to do is detect the inconsistency with the rising edge as shown in the attached image, it should be smooth like the falling edge. I have thought about doing this by sampling the gradient along the rising edge and then having a trigger to say whether it is within acceptable limits. For this signal, the gradient would turn to negative thus triggering the alert.
Now my problem is I have no idea how to do this in LabVIEW and would really appreciate if anyone could point me in the right direction, or has a better way of detecting a fault like this.

This is my first time posting on the NI forums, if there is something I should be doing differently to get responses could someone let me know, please.

Hi B²,
sampling the gradient along the rising edge and then having a trigger to say whether it is within acceptable limits.
You can also try to detect when your signal has reached a "stable" range by just calculation a running min/max/mean. When the value doesn't change "a lot" for a settable amount of time/samples then you reached the HIGH/LOW level…
