摘要：
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\(s)g(xl\x\(1+beta)), where g is a L-p indefinitely oscillating function like sin(x). Under suitable assumptions, we achieve a characterization of the chirps by means of their wavelet transforms. (C) 1997 Academic Press.
