| Abstract: | In this paper, interpolation formulas are derived for the recovery of a two-dimensional (2-D) bandlimited signal from its isolated zeros. Different constellations of zero locations are considered. The interpolation formulas, based on Lagrange interpolation, are given both in Cartesian and in polar coordinates. |
