Name: Overview of Fast Fourier Transform (FFT) Algorithms
ID: m12026
Language: English (en)
Summary: Fast Fourier transform (FFT) algorithms efficiently compute the discrete Fourier transform (DFT). There are different types of FFT algorithms for different DFT lengths; lengths equal to a power of two are the simplest and by far the most commonly used. The prime-factor algorithm yields fast algorithms for some other lengths, and along with the chirp z-transform and Rader's conversion allow fast algorithms for DFTs of any length.
