A function \(f\) with compactly supported Fourier transform can be approximated by a step function \(a\) which coincides with \(f\) at regularly spaced points \(s k, k \in \mathbb{Z}\). For suitable \(s\), the functions \(f\) and \(a\) have the same \(L^{2}\) norm. By modifying \(a\) so that its Fou

We define the Laplace transformation for elements of Colombeau's spaces \(\mathscr{\varphi}_{c}\left(\mathbf{R}^{n}\right), \mathscr{G}_{c}^{x}\left(\mathbf{R}^{n}\right)\) and \(\mathscr{G}_{1}(\Gamma)\), where \(\Gamma\) is a cone. We obtain, in Theorems 1,2 , and 4 , the "expected" Paley-Wiener t
