Abstract. We will discuss the problem of finding the best approximations
in the space of real sequences. We introduce orthogonal sequences using
Z-Transform and apply it in approximating of inverse Z-Transform. We will
illustrate it by some examples.
Key words: Approximation, Orthogonal Functions, Z-Transform.
JEDAN METOD ZA NUMERIČKO
IZRAČUNAVANJE INVERZNE Z-TRANSFORMACIJE
U radu proučavamo problem nalaženja najbolje aproksimacije u prostoru realnih
nizova. Stoga, koristeći Z-transformiju, uvodimo ortogonalne
nizove. Ove nizove upotrebljavamo u aproksimiranju inverzne
Z-transformacije. Metod ilustrujemo odgovarajućim primerima.
