摘要
Very recently, Sonker and Singh [21] determined the degree of approximation of the conjugate of 2 pi-periodic signals (functions) belonging to Lip(alpha, r)(0 < alpha <= 1, r >= 1)-class by using Cesaro-Euler (C,1) (E,q) means of their conjugate trigonometric Fourier series. In the present paper, we generalize the result of Sonker and Singh [21] on the generalized weighted Lipschitz W(L-r, xi(t)), (r >= 1) - class of signals (functions) by product summability (C,1) (E,q) transform of conjugate trigonometric Fourier series. Our result also generalizes the result of Lal and Singh [6]. Few applications and example of approximation of functions will also be highlighted.
