- Sampling theory is one of the most powerful results in information theory and technology.The objective of sampling is to reconstruct a digital signal from its samples.Walter and Zhou extended the Shannon sampling theorem to wavelet subspaces.For a given digital signal f∈L2(R),whether it has sampling series form.In this paper,based on wavelet frames,we offer some new results which give conditions of sampling functions.For some sampling spaces,the based sampling functions are explicitly given.
