WebFFT (Fast Fourier Transform) refers to a way the discrete Fourier Transform (DFT) can be calculated efficiently, by using symmetries in the calculated terms. The symmetry is highest when n is a power of 2, and the … A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by decomposing a sequence of values into components of different frequencies. This operation is useful in many fields, but computing it directly from the definition is often too slow to be practical…

The first one is minor, the FFT is 'out of scale', so I apply a scaling factor mean (y)/mean (curve) to fix it, which is a bit of a hack. I'm not sure why this is the case.

WebJan 9, 2016 · The frequency for the center of each bin would be: 2.4 GHz - 3.75 MHz, 2.4 GHz - 1.25 MHz, 2.4 GHz + 1.25 MHz, and 2.4 GHz + 3.75 MHz. As Andy indicated, choosing an FFT bin size that is a power of 2 allows you to calculate the FFT using the more efficient DFT algorithm. cheers, Denny. Last edited: Jan 9, 2016. T.
