I have a waveform graph, obtained from a Spectrum Analyzer. The axis are amplitude and samples, but I want to change this axis, and convert samples to frequency. how can this be done? thanks
You use an FFT to convert from the time to the frequency domain. There are several shipping examples. Go to the example finder and enter spectrum on the search tab. For a waveform data type you can use the function FFT Power Spectrum. To use any of the FFt functions, you must have at least the full version of LabVIEW. The base version doesn't come with them.
