In this paper a simple method of approximation of discrete time windows is proposed. The approximation by the 3-rd order polynomial windows leads to better results than commonly used methods based on expanding the cosinus function into series, as shown in Figures 4 and 5. The formulas for calculations of the discrete spectral characteristics have been introduced. They can be the basis for determining the spectral properties of the higher order discrete polynomial windows.(fragment of text)
