WebAug 4, 2006 · The time-frequency and time-scale communities have recently developed a large number of overcomplete waveform dictionaries---stationary wavelets, wavelet packets, cosine packets, chirplets, and warplets, to name a few. Decomposition into overcomplete systems is not unique, and several methods for decomposition have been proposed, … WebMay 31, 2010 · In such a case, chirplets (or chirp signals of limited time extent) can be thought of as a good model of the underlying signal—any narrowband changes in instantaneous frequency can be described mathematically to first order by linear changes in the time-frequency plane [ 34 – 36 ]. WebDec 1, 2013 · Chirplets are a class of signals that consist of Gaussian kernels that are translated in time and frequency, scaled and chirped.

In signal processing, the chirplet transform is an inner product of an input signal with a family of analysis primitives called chirplets. Similar to the wavelet transform, chirplets are usually generated from (or can be expressed as being from) a single mother chirplet (analogous to the so-called mother wavelet … See more The term chirplet transform was coined by Steve Mann, as the title of the first published paper on chirplets.
