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 • Fractional Fourier transform 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: for an arbitrary 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 WebNov 17, 2014 · A chirp is a form of frequency modulation. You can look up what kinds of spectrum sidebands are formed around a carrier sinusoid by various forms of modulation. – hotpaw2 Nov 17, 2014 at 17:04 1 Sorry but I am quite new to this kind of topics and I think I do not really get what you mean – Rhei Nov 17, 2014 at 17:10 1
