Abstract.
This paper presents a method for determining the sensitivity of the systems, working at high frequencies, such as telecommunications systems. It was shown that the continuous system is the most sensitive related to the parameters with the highest index, and the least sensitive related to the parameters with the lowest index and vice versa for discrete systems. Validity of the results is confirmed by experiments.
Key Words:
sensitivity, system parameters, transfer function, frequency.
O OSETLJIVOSTI TELEKOMUNIKACIONIH SISTEMA
U ovom radu je predstavljen jedan metod određivanja osetljivosti sistema, koji rade na visokim učestanostima, kao što su telekomunikacioni sistemi. Pokazano je da je kontinualni sistem najosetljiviji na parametar sa najvišim indeksom, dok je najmanje osetljiv na parametar sa najnižim indeksom, dok kod diskretnih sistema važi obrnuto. Validnost rezultata je potvrđena eksperimentima.
Ključne reči:
osetljivost, parametri sistema, funkcija prenosa, frekvencija
