We present the windowed Fourier transform and wavelet transform as tools for analyzing persistent signals, such as bounded power signals and almost periodic functions. We establish the analogous Parseval-type identities. We consider discretized versions of these transforms and construct generalized

Abstract
In this paper, we study the inversion formula for recovering a function from its windowed Fourier transform. We give a rigorous proof for an inversion formula which is known in engineering. We show that the integral involved in the formula is convergent almost everywhere on \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$\mathbb {R}$\end{document} as well as in L^p^ for all 1 < p < β if the function to be reconstructed is.

Most methods for the numerical calculation of inverse Laplace transformations f(t) = L -1 [F(s)] have serious limitations concerning the class of functions F(s) that can be inverted or the achievable accuracy. The procedures described in the paper can be used to invert rational as well as irrational
## Abstract Consider the Poincare unit disk model for the hyperbolic plane **H**^2^. Let Ξ be the set of all horocycles in **H**^2^ parametrized by (__ΞΈ, p__), where __e^iΞΈ^__ is the point where a horocycle __ΞΎ__ is tangent to the boundary |__z__| = 1, and __p__ is the hyperbolic distance from __ΞΎ_
Recently we published two explicit formulae for finite inverse Hilbert transforms (You and Zeng, Inv Probl 22 (2006), L7-L101). This paper presents a straightforward proof of the formulae, the data requirements, and some computer simulations to verify the formulae. Examples of region-of-interest tom
