Summary:FIELD: automation and computer engineering. SUBSTANCE: device has memory units 1, 5, and 8, multipliers 6, 10, 11, 12, 13, 14, adder 15, register 16, control unit 3, counter 2, fast Fourier transform unit 4, fast reverse Fourier transform unit 7, spline parameters generation unit 9. Goal of invention is achieved by means of use of a priori information about function smoothness and taking into account complete array of function samples. EFFECT: increased precision of interpolation for functions with continuous fourth derivative. 2 cl, 7 dwg
