Hello, I am new to LabView and I am working on a project in which I have to analyze an analog signal with the spectral measurements VI.
What I want to achieve is to get a spreadsheet with the dominant frequencies of the signal and their amplitudes.
In my personal computer I don´t have access to a DAQ so what I did is this:
- I simulated three sinusoidal waves with white noise.
- I added them together
- I analyzed them with the spectral measurements Vi (Power Spectrum).
- I created a waveform graph for the output signal.
- I write that output data to a spreadsheet
In the spreadsheet I get the amplitude values (50 samples I don´t know why) but I can´t find a way to get the frequencies of that amplitude.
Thanks in advance.
