Analysis of critical sampling effects revisited

摘要

In the paper, some specific problems occurring in analysis of critically sampled signals and their reconstruction are considered. These are the problems which are mostly omitted in the literature of the subject because they can lead to ambiguous results. Because of this reason, their explanation is hard and thankless. Here, we show how to find and verify the general description of the resulting signal by usage of Dirac delta and sinc, and Π functions.
