WebOct 19, 2024 · 1. LabVIEW includes a point-by-point FFT function that outputs an array representing the FFT result with each input sample. As I recall, you input the array size of the result that you need. The function takes some time to settle, meaning that you will need to input some number of samples before the results are meaningful. WebMar 13, 2015 · Common trick: take FFT of known signal and normalize by the value of the peak. Say in the above example your peak is 123 - if you want it to be 1, then divide it ( and all results obtained with this algorithm) by 123.
