Some Questions about Realization of Approximation Methods of Dynamic System Signal Processing in the Program Environment of Software Mathematics

摘要

The algorithmic and programming aspects of the dynamic system signals approximation is considered via use of the symbolic mathematics software Mathematics of Wolfram Research Inc. The special notice is taken of the orthogonal systems of the pulse type basis functions like Well-known Walsh functions, Rademaher functions, etc. The comparative analysis of the known And proposed methods of polynomial approximation is performed.
