I have a pretty basic need for the filtering capabilities of LabVIEW. We measure accelerometer data over a period of time and filter out all frequenicies that are above 500 Hz.
Essentially, I need a program that reads from a 2 column, tab-delineated text file, puts a 500 Hz lo-pass filter on the data, and saves to a new file.
Below is a very simple block diagram, along with the filter settings, and the error I receive, when I attempt to run it with data obtained from a previous test that was not filtered.
Solved! Go to Solution.

The file is 2 columns, G forces and time.
I thought maybe it wasn't working because the .vi might only take a live signal, rather than a stored data file. Not sure about that though.

Well, I am making progress, thanks for the help. Still getting an error though.

You are correct, but I still get the error message.
