Counting Analog Rising Edges when Passing Threshold in LabVIEW

[Efrain_G]

 Overview

This example shows how to count how many times a signal crosses a threshold while increasing only

Description

This example shows how to count how many times a signal passes a threshold while increasing only. This means that if the signal crosses the threshold while it is decreasing, this will not be counted.

Requirements

LabVIEW Base Development System 2012 or compatible

Steps to Implement or Execute Code

1. Enter the Threshold value
2. Enter the Input Signal values
3. Run the VI
4. Notice that Counter shows the number of times the signal rises above the Threshold

Thanks for the example helped me a lot.

Thank You greatly for this code...it helped me a lot. But, in order for you to get rising edges you need to switch the two values shown. They're backwards.
