Method of digital filtration of experimental data sequences with the use of approximation spline functions

A method of digital filtration of experimental data sequences with the use of approximation spline functions is proposed. A problem of digital filtration on the basis of such functions is posed, and its general solution is given. An example of constructing approximation spline functions with control at the ends of observation intervals is considered. Results of digital filtration of aerodynamic experimental data with the use of the method developed are described.
