<DIV>I have an input signal that goes from value 0.1 to 3 then back to 0.1.  There is a situation where the signal can come in starting inverted at 3 going to .1 then back to 3.  Is there a math function or anything similar I can do to check which signal I am getting.  My thoughts were to calculate the slope of the initial and end portions of the data and check if the numbers are positive or negative respectively.</DIV><p>__________________________________________________
