WebAug 2, 2024 · The standard chirplet transform (CT) with a chirp-modulated Gaussian window provides a valuable tool for analyzing linear chirp signals. The parameters present in the window determine the performance of the CT and play a vital role in high-resolution time-frequency (TF) analysis. In this paper, we give the window shape analysis of the CT and … In signal processing, the chirplet transform is an inner product of an input signal with a family of analysis primitives called chirplets.
