An approximate solution of the refinement equation is given by its mask, and the approximate sampling theorem for a bivariate continuous function is proved by applying the approximate solution. The approximate sampling function defined uniquely by the mask of the refinement equation is the approximate solution of the equation, a piecewise linear function, and possesses an explicit computational formula. Therefore the mask of the refinement equation is selected according to the requirement that the decay speed of the approximate sampling function can be controlled.
