标题：Degree of approximation of conjugate of signals (functions) belonging to the generalized weighted Lipschitz $W(L_r,\psi(t))$, $(r\geq 1)$-class by $(C,1)(E, q)$ means of conjugate trigonometric Fourier series
摘要：Very recently, Sonker and Singh [21] determined the degree of ap- proximation of the conjugate of 2π-periodic signals (functions) belonging to Lip(α,r)(0 < α ≤ 1,r ≥ 1)-class by using Cesàro-Euler (C,1) (E,q) means of their conjugate trigonometric Fourier series. In the present paper, we general- ize the result of Sonker and Singh [21] on the generalized weighted Lipschitz W(L r ,ξ(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.
