Метод экстраполяции в цифровых интегрирующих структурах

Abstract

The extrapolation method of Stieltjes integral by means of on-line arithmetic in symmetric redundant notations is proposed. In comparison with known difference schemes of digital integrating structure (DIS) construction it allows to overlap an extrapolation with integral increment caclculations on each integration step with the same order of accuracy. The method creates preconditions for productivity improvement of DIS, realizing nonautonomous integral calculations, in 1,5-2 times. Also the appropriate schematic is proposed.
