Using a baseband an even number of knots, we define a symmetric iterative interpolation process. The main properties of this process come from an associated functionF. The basic functional equation forFis thatF(t/b) =. We prove that F is a continuous positive definite function. We find almost precisely in which Lipschitz classes derivatives ofFbelong. If a functionyis defined only on integers, this process extendsycontinuously to the real axis as. Error bounds for this iterative interpolation are given.
