WebMay 6, 2015 · A linear chirp or linearly swept sine is a signal in which the frequency changes linearly with time: the starting frequency changes into the ending frequency over time at a rate of: and is the amount of time it takes. Its instantaneous frequency at point t is: It looks like this: 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". crystal travel agency london https://riflessiacconciature.com
