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". WebThe 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.
