SU1388908A1 - Extrapolator - Google Patents

Abstract

This invention relates to analog computing. The purpose of the invention is to expand the scope by providing simultaneous extrapolation of the input signals at one scale and at the same time eliminating the need to adjust each channel. The extrapolator contains 1 clock pulse generator, 2 saw voltage generator, 3 support voltage source, extrapolation function formation blocks 44-4, 5j quad, first, second and third algebraic adders 6-8, tires 9, -9 l assigning the ordinates of the extrapolated function, outputs 10, -10. Block 4 contains multipliers, analog shift register, algebraic adder. Auxiliary functions of second-order time are periodically formed at the outputs of algebraic adders, multiplied in blocks 4 by the corresponding values of the ordinates of extrapolated functions arriving at the inputs with the same period. At outputs 10, second-order extrapolating polynomials are formed. 1 hp f-ly, 2 ill. (L
