Abstract: This paper concentrates on the Lebesgue functions of rational interpolation of non-band-limited continuous time signals. Approximation based on sampling and interpolation are cornerstones of ...

A horizontal asymptote is a horizontal line that a function approaches as the input variable (usually denoted as x) goes towards infinity or negative infinity. Understanding how to find horizontal ...

Abstract: Graph Fourier transform (GFT) is an important tool for analyzing the irregular graph signals collected from various real-world networks. One of its applications is the graph Fourier ...

Introduction: The domain of a function is the set of all possible input values (x-values) for which the function is defined. Understanding the domain is crucial for solving mathematical problems and ...
