Sampling operators constitute a class of linear and nonlinear mappings designed to reconstruct or approximate functions from discrete data. Rooted in classical Shannon theory, modern developments ...

Sampling theory in shift-invariant spaces extends classical bandlimited reconstruction to a broad class of function spaces generated by the integer shifts of one or more prototype functions. In this ...

Over the years, I've encountered many engineers (a majority in fact) who are still puzzled by the subtleties of sampling. Even though they may know some mathematical basics, or have some idea of how ...
