The chirp Z-transform (CZT) is a generalization of the discrete Fourier transform (DFT). While the DFT samples the Z plane at uniformly-spaced points along the unit circle, the chirp Z-transform samples along spiral arcs in the Z-plane, corresponding to straight lines in the S plane. The DFT, real DFT, and zoom DFT can … See more Bluestein's algorithm expresses the CZT as a convolution and implements it efficiently using FFT/IFFT. As the DFT is a special case of the CZT, this allows the efficient calculation of discrete Fourier transform See more • A DSP algorithm for frequency analysis - the Chirp-Z Transform (CZT) • Solving a 50-year-old puzzle in signal processing, part two See more Bluestein's algorithm can also be used to compute a more general transform based on the (unilateral) z-transform (Rabiner et al., 1969). In … See more • Fractional Fourier transform See more Web‘‘chirp transform algorithm’’ which is a special case of the ‘‘chirp-z. transform.’’ The chirp-z. transform is well-known and can be used to evaluate quadratic chirps. The method described in our paper is general and not constrained to qua-dratic chirp functions. We call the algorithm described in this paper the ‘‘fast chirp ... Web* The chirp z-transform.
