LabVIEW
problem in signal processing
Hello all,
I use LabVIEW 8.2 student edition. I have the problem to split the output of FFT.
The harmonic component has more then one output:
Can I get only one of the component in harmonic component? I mean, in the result picture, there are three outputs. Can I get the first one only (in DBL type)? How to split the signal?
In the plot, the horizontal axis of the plot is time. Can I divide the number of the axis? I mean, it is written 100, 200, 300, 400, so on. Can I show it as 1, 2, 3, 4, so on?
Thank You for all the help.

Hi Fikri,
first: DON'T save your picture as bmp, they take very long to load... Use png or jpg instead!
"Can I get the first one only?" - Use the "Index array" function to get the first element of the array.
"Can I show it as 1, 2, 3, 4, so on?" - Set the multiplier of the x-axis to 0.01 in the graph properties.
From your questions I also would advise to take some LabView lessons, there are 3 and 6 hour courses at the ni website! Have a look at the examples that come with LabView. RTFM.
