Chirp algorithm
Webchirp: [verb] to make a chirp or a sound resembling a chirp. Web12/03/2024 CTA, CZT 13 Chirp z-Transform (CZT) Going off the unit circle using a spiral. Getting closer to points in the z-plane. Amplifying buried poles. One, simple generalisation compared to CTA: “Radial gain” added to “tangential binning”. Traditional inverse via IFFT, but that is slow. Direct, fast inverse exists since 2024.

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 …
WebThe time gap and the distance can be used to measure sound speed. The experimental results show that the chirp signal improves the signal-to-noise ratio and expands the applicable time-of-flight algorithm. The waveform pulse width after cross-correlation is 1.5 μs, compared with 40 μs before. WebChirp definition, to make a characteristic short, sharp sound, as small birds and certain insects. See more.
