Product Summability Transform of Conjugate Series of Fourier Series
A known theorem, Nigam 2010 dealing with the degree of approximation of conjugate of a signal belonging to Lipξ t -class by E, 1 C, 1 product summability means of conjugate series of Fourier series has been generalized for the weighted W Lr, ξ t , r ≥ 1 , t > 0 -class, where ξ t is nonnegative and increasing function of t, by ̃ E1 nC n which is in more general form of Theorem 2 of Nigam and Shar...
متن کاملApproximation of signals belonging to generalized Lipschitz class using-summability mean of Fourier series
Abstract: Degree of approximation of functions of different classes has been studied by several researchers by different summability methods. In the proposed paper, we have established a new theorem for the approximation of a signal (function) belonging to the W(L r , (t))-class by (N, p n , q n )(E, s)-product summability means of a Fourier series. The result obtained here, generalizes several...
متن کاملDEGREE OF APPROXIMATION OF FUNCTIONS BELONGING TO LIPα CLASS AND WEIGHTED (L,ξ(t)) CLASS BY PRODUCT SUMMABILITY METHOD
A good amount of work has been done on degree of approximation of functions belonging to Lipα, Lip(α, r), Lip(ξ(t), r) and W (L, ξ(t)) classes using Cesàro and (generalized) Nörlund single summability methods by a number of researchers like Alexits [1], Sahney and Goel [11], Qureshi and Neha [9], Quershi [7, 8], Chandra [2], Khan [4], Leindler [5] and Rhoades [10]. But till now no work seems to...
متن کاملApproximation of optical signals by the vortex eigenfunctions of the double finite Hankel transform
This study considers a class of double finite Hankel transforms that describes the transmission of a vortex optical signal through a two-lens system with limited aperture radii in the object and spectral flats. The eigenfunctions of the given transform are calculated for different orders of vortex m. The functions obtained are an orthonormal system of functions, which can help expand an unspeci...
متن کاملB–statistical A–summability in Conservative Approximation
This paper deals with the approximation of functions by sequences of linear operators via B -statistical A -summability. Quantitative results and asymptotic formulae are stated under a conservative approximation setting. A short discussion is addressed in connection with the rate of statistical convergence. Finally, the applicability of the results is illustrated. Mathematics subject classifica...
