In this article, we propose a general model for some chirp-like signal
s, 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
