Comparator ?

[Harald Noack]

Hello!

Has anyone of you programmed a comparator with inputs for reference and
hysterese and outputs if the signal is over or under the reference?

If yes please help me and send me the vi!

THANKS a lot !!!

find attached a simple comparator.vi - not made by me.
It should be no problem to add hysteresis....

hope this helps
regards

I have seen examples of this kind of program, but I cannot remember where they are. I wrote the attached program to make a high limit sticky--signal goes high at .7 and stays high until the input goes below .4. I think this program demonstrates a technique so that you can write the code you want.
