Abstract

Many researchers have looked into various linear summation techniques for approximating periodic functions. In the current paper, an attempt is made to obtain the degree of approximation of signals belonging to weighted $(L^\mu,\varphi(v)) $ class by Zweier-Euler product of its Fourier series.

Keywords and Phrases
