Abstract
The sampling theorem is one of the most powerful results in signal analysis . In this paper, we study the average sampling on shift invariant subspaces , e.g. wavelet subspaces. We show that if a subspace satisfies certain cond itions, then every function in the subspace is uniquely determined and can be reconstructed by its local averages near certain sampling points. Exampl es are given.
