Abstract :
This article presents a new procedure for the recovery of a signal from its nonuniform samples based on the root distribution of a given function; as an example, an orthonormal sampling expansion analogue to the Shannon expansion is shown to be useful in the recovery. We also extend the concept of a “bandlimited signal” to transformed domains other than the Fourier domain
