WebDec 1, 2024 · Hence, the chirplets that rotate in different angles at different frequency centers can exactly match all trajectories of the target multi-component signal if parameter a is set properly. We still take the signal x 2 (t) as an example to clarify the core thought behind CMCT. Similarly, we present this example in a window length range. WebGaussian Windowed Chirps (Chirplets) As discussed in § G.8.2, an interesting generalization of sinusoidal modeling is chirplet modeling. A chirplet is defined as a Gaussian-windowed sinusoid, where the sinusoid has a constant amplitude, but its frequency may be linearly ``sweeping.''
