New methods of approximation of step functions with estimation of error of the approximation are suggested. The suggested methods do not have any disadvantages of traditional approximations of step functions by means of Furrier series and can be used in problems of mathematical modeling of wide range of processes and systems.
Keywords: step functions, mathematical modeling, approximation, estimation of error, examples of using.
Mots-clés : convergence
