The classical sampling theorem has often been attributed to E.T. Whittaker, but this attribution is not strictly valid. One must carefully distinguish, for example, between the concepts of sampling and of interpolation, and we find that Whittaker worked in interpolation theory, not sampling theory. Again, it has been said that K. Ogura was the first to give a properly rigorous proof of the sampling theorem. We find that he only indicated where the method of proof could be found; we identify… 
Sampling Theory in a Fourier Algebra Setting
Sampling theory has been studied in a variety of function spaces and our purpose here is to develop the theory in a Fourier algebra setting. This aspect is not as well-known as it might be, possibly
The sampling theorem, Poisson's summation formula, general Parseval formula, reproducing kernel formula and the Paley–Wiener theorem for bandlimited signals – their interconnections
It is shown that the Whittaker–Kotel'nikov–Shannon sampling theorem of signal analysis, which plays the central role in this article, as well as (a particular case) of Poisson's summation formula,

This paper introduces a sampling theorem for periodic functions, and gives its physical meaning; this theorem is effective for functions that can be expressed as a finite Fourier series in the same way as WOKSS's theorem deals with a band-limited signal.

This talk centers on a tutorial review of the various aspects of the multivariate sampling for the past sixty years, since it was suggested by Parzen in 1956.
Signal and System Approximation from General Measurements
This paper analyzes the behavior of system approximation processes for stable linear time-invariant systems and signals in the Paley–Wiener space PW π and shows that a stable system approximation is not possible for pointwise sampling, but if more general measurement functionals are considered, a stable approximation is possible if oversampling is used.
An interactive approach for illustrating a proof of the sampling theorem using MATHEMATICA
The goal of this work is to show that learning the sampling theorem through an interactive example of its mathematical proof can be an enjoyable and insightful experience.
Strong divergence for system approximations
This paper analyzes approximation of stable linear time-invariant systems, like the Hilbert transform, by sampling series for bandlimited functions in the Paley–Wiener space PWπ1 by proving strong divergence, i.e., divergence for all subsequences.

Fundamental Properties of RKHS
The general theory of reproducing kernels and its fundamental properties are developed, and it is established that any positive definite kernel corresponds uniquely to an RKHS.
Signal and System Approximation from General Measurements
It is shown that a stable system approximation is not possible for pointwise sampling, because there exist signals and systems such that the approximation process diverges, but if more general measurement functionals are considered, a stable approximation is possible if oversampling is used.


Some general aspects of the sampling theorem
The sampling theorem is recognized as an interpolation formula and extended to include sampling of the first derivative of the function to aid the formulation of particularly applicable sampling theorems for specific problems.

Sampling Theory for not Necessarily Band-Limited Functions: A Historical Overview
The aim of this overview is to show that one of its roots is a basic paper of de la Vallee Poussin of 1908, and the historical development of sampling theory from 1908 to the present, especially the matter dealing with not necessarily band-limited functions.
