Some new results concerning the accelerating convergence of univarlate and bivariate Fourier expansions are presented. The rate of convergence is estimated with respect to the uniform norm.This acceleration method is a combination of algebraic and trigonometric approximation. Note that the abstract Taylor formula is an essential tool of this approach.
