Web8-D "chirplet space" (with appropriate smoothing kernel). Furthermore, the chirplet transform is a framework for deriving new signal represen-tations. The chirplet transform is a mapping from a 1 -D domain to an 8-D range (in contrast to the wavelet, for example, which is a 1 -D to 2-D mapping). Display of the 8-D space is at best difficult.
