In mathematics and signal processing, Bluestein’s algorithm is a method for computing the discrete Fourier transform of sequences of arbitrary length. The algorithm transforms the DFT into a convolution that can be efficiently evaluated with the fast Fourier transform, making it useful for applications that require flexible transform lengths, such as spectral analysis and digital filtering. The method is widely cited in textbooks and scholarly articles and is implemented in many numerical libraries.
