Chirp transform algorithm
WebThe Chirp z-Transform Algorithm Abstract: A computational algorithm for numerically evaluating the z-transform of a sequence of N samples is discussed . This algorithm has been named the chirp z-transform (CZT) algorithm . WebThe Chirp-Z transform lets you evaluate any evenly-spaced set of frequencies along the unit circle (or even along an arc inside the unit circle, but we'll ignore that right now). Imagine you have a 256-element-long vector, and you'd like to compute the DFT at a more finely-spaced set of samples, but over a narrow range (the so-called "zoomed FFT".
