Extrapolation and interpolation of processes using their natural spectrums |
Dmitriev E.V.
The article deals with the task of approximation and forecasting the under study process by its known fragment. Under approximation the known fragment is factorized to oscillation components by calculation results of its natural harmonic spectrum. The conditions for effective process extrapolation, including that distorted by noise are formulated. The illustrative examples are given.
Key words: processes, approximation, extrapolation, line spectrum, non-orthogonal harmonics.
