Abstract
In this article, we develop a one parameter family of cardinal interpolants associated to a function ϕ. The main theorem gives conditions on ϕ and the parameter that allow Paley-Wiener functions to be recovered from their samples on the integer lattice \(\mathbb {Z}^{n}\). Our methods unify previous work done on splines and the Gaussian and provide new examples of this phenomenon, including two families of multiquadrics.
