Fast Fourier transform 快速傅里叶变换

(重定向自FFT)
 Time signal of a five term cosine series. Frequencies are multiples of 10 times sqrt(2). Amplitudes are 1, 2, 3, 4, 5.  Time step is 0.001 s

A fast Fourier transform (FFT) algorithm computes the discrete Fourier transform (DFT) of a sequence, or its inverse. Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. An FFT rapidly computes such transformations by factorizing the DFT matrix into a product of sparse (mostly zero) factors. As a result, it manages to reduce the complexity of computing the DFT from O(n^2), which arises if one simply applies the definition of DFT, to O(n \log n), where n is the data size.
