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 particular, it can compute any transform of the form: See more • Fractional Fourier transform See more
WebDec 1, 2006 · Multiple Modulation Zoom Spectrum Analysis (ZFFT) and the Chirp-Z Transform (CZT) are widely used methods in the zoom spectrum analysis. A specific … WebThis algorithm has been named the chirp z-transform algorithm. Using this algorithm one can efficiently evaluate the z-transform at M points in the z-plane which lie on circular or spiral contours beginning at any arbitrary point in the z-plane. The angular spacing of the points is an arbitrary constant; M and N are arbitrary integers.
Webdiscrete Fourier transform can be conveniently generalised using the z-transform and z-plane. CTA adds flexibility to the DFT by allowing a high resolution subsampling of an arbitrary arch on the unit circle. It still maintains N log N performance. CZT, the generalised CTA, evaluates the z-transform along a spiral contour of the z-plane. WebAmong the signal processing methods of Doppler weather radar, the FFT (Fast Fourier Transform) method is widely used. If the measurement accuracy needs to be improved, the number of FFT points also needs to be increased. As a result, the amount of computation increases exponentially.
