Hey guys
This question is a spin-off of another question, but the scope has changed.

How do I detect any fluctuation of a constant voltage in positive or negative direction when it move outside +/- 20mV from zero volts? I am receiving an analog pulse in 1 - 5 second intervals and I need to detect the starting point of the pulse with a 10- 20 micro seconds accuracy. The catch is that I don't know if the pulse is going to go down or up first. I had a look at Schmitt triggers, but I don't think that is going to work for this application?
Any ideas is appreciated.
