The goal of this article is that of understanding how the oscillation and
concentration effects developed by a sequence of functions in $\mathbb{R}^{d} $
are modified by the action of Sampling and Reconstruction operators on regular
grids. Our analysis is performed in terms of Wigner and defect measures, which
provide a quantitative description of the high frequency behavior of bounded
sequences in $L^{2}(mathbb{R}^{d}) $. We actually present explicit formulas
that make possible to compute such measures for sampled/reconstructed
sequences. As a consequence, we are able to characterize sampling and
reconstruction operators that preserve or filter the high-frequency behavior of
specific classes of sequences. The proofs of our results rely on the
construction and manipulation of Wigner measures associated to sequences of
discrete functions.
