| Abstract: | In this article, we propose a general model for some chirp-like signals. The analytical structure of these chirps is given in the form |x|sg(x/|x|1+β), wheregis aLpindefinitely oscillating function like sin(x). Under suitable assumptions, we achieve a characterization of the chirps by means of their wavelet transforms. |
