WebThe LabVIEW analysis virtual instruments (VIs) in the Signal Processing palette maximize analysis throughput in FFT-related applications. This application note discusses some FFT properties, how to interpret and display FFT results, and how to further manipulate FFT and power spectrum results to extract useful frequency information. WebFFT function. Below, you can see what an FFT of a square wave looks like on a mixed-signal graph. If you zoom in, you can actually see the individual spikes in the frequency domain. Back Next Figure 6. The frequency domain of a sine wave looks like a ramp. Figure 7. The original sine wave and its corresponding FFT are displayed in A, while B is a

The signal has been sampled at 10kHz. The output from the FFT VIs are integer values e.g.. 1,2,3,4,5..... I am looking for 2 particular frequencies at 14.3Hz and 15.1 Hz. Just now I get a peak at 14 and 15 but I want to be more specific. Is this possible? Thanks Scott 0 Kudos praying mantis green or brown
