| Abstract: | Positive convoluiton operators have been proven to be great use in the theory of approximation. It is well known that the degree of approximation of peridic functions by positive operators has certain limitations. Therefore, in order to improve the degree of approximation, it is important to modify the form of operator suitably. In this paper we have obtained the degree of approximatimation by typical Gverage of Fourier series Qn (f,x) in spaces C and Lp |
