average value

[maria2]

Hi,

I need to determine the average value of an input signal. I'm not able to use the built-in block of LabView 7.1 because it needs the file mean.vi, which I don't have.

I've also tried to calculate the average value by the definition: X_average=integral(X)/time
but I can't find a way to use the required "time".

Is there any simpler way of doing this?

Thank you!

I'm not sure why you wouldn't have the Mean function. I thought it was included in all versions of LabVIEW. Have you tried to do a seach for it?

In any case, you can also use the Add Array Elements function. Take the result and divide by the number of elements.

Hi,

Thank you for your message.
In fact, that file doesn't exist on my computer. Where could I download it?
I will also try your suggestion.

Thank you.

On my computer, the Mean.vi resides in the functions palette -  Analyze - Mathematics - Probablilty & Statisctics.  It can also be found in your Labview folder/vi.lib/analysis/baseanly.llb.  Here it is in the attached file.

Thank you for the file!
