Chirp transform algorithm

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.
