• Approximation of functions of different classes have been considered by various researchers under different summability means. In the present paper, presumably a new theorem has been established under (E, 1)(N̅ pn) -product summability mean of conjugate Fourier series of a function of Zr(⍵) r (r ≥ 1) -class (generalized Zygmund class). Moreover, the result obtained here is a generalization of several known theorems.
