WebFeb 23, 2024 · LabVIEW Owning Palette: Spectral Analysis PtByPt VIs Requires: Full Development System Computes the signal energy distribution in the joint time-frequency domain using the short-time Fourier transform (STFT) algorithm. This VI performs a sliding FFT. This VI is similar to the STFT Spectrograms VI. WebIt is important to note that the STFT window length N w directly drives frequency resolution, which is f s /N w, where f s is the sample rate. The window size must be shorter than the spacing between transient impulses, but longer than the individual transient impulses. References [1] Antoni, J. "The Spectral Kurtosis: A Useful Tool for ...
