Annotation: Аn algorithm for approximation of a large data set has been proposed. A comparison of the new algorithm and the polynomial approximation for the case of the approximation of the delay per unit length of transmission lines in a wide range of parameters of the basic structures of printed circuit boards has been performed. The performance of the proposed algorithm and the possibilities of its improvement have been described.

Keywords: data approximation, printed circuit board, analytical models, polynomial approximation
