Windowed FFT

Solved!
Go to solution

Hi. I really need a help. I have an excel data and then I use a Real FFT vi to get the frequency spectra of data/wave. Now, I want to use windowed FFT with the same excel data, but was fail. Input for real FFT is a vector, while input for windowed FFT is a point. Can someone help me how to use the excel data for input of windowed FFT?; or maybe someone can give me an advice using "spectral measurement". Thank you in advance.

Why not use the Symmetric Window VI before the FFT VI?  It accepts arrays and gives you choices fo all the common windows.  It is in the Signal Processing >> Windows palette.
