the technical tag   The tag says  This article may be too technical for most readers to understand Please help improve this article to make it understandable to nonexperts without removing the technical details The talk page may contain suggestions  So I am creating this place for suggestions  My own assessment is different  I think there are probably too many technical details such as critical frequency nonbaseband sampling nonuniform sampling undersampling and multivariable sampling that could be relegated to the See Also list if we need to make the article less intimidating  The actual discussion of the theorem itself has excellent figures and is in my opinion readily understandable to those with a working knowledge of the Fourier transform which seems to be a universally assumed prerequisite
