Proračun šuma PP filtra 4.reda u CBQ strukturi

Kroz ovaj diplomski rad opisan je postupak projektiranja, analize te u konačnici realizacije pojasnopropusnog filtra 4.reda u kaskadnoj strukturi te kaskadi bikvarta. Analiza i simulacije provedene su korištenjem programa MATLAB te LTSpice. Nakon dobivanja željenih rezultata izrađen je praktični model filtra. Ispravnost izrade potvrdila se mjerenjem osciloskopom, a potom su izvršena mjerenja mrežnim analizatorom te je tako potvrđena ispravnost proračunatih elementa filtra. Dolazi se do zaključka kako filtar ispravno radi te se može proizvesti u realne svrhe te je zadatak diplomskog rada uspješno izvršen.This thesis consists of an overview of a process of design, analysis and realization of the 4th order bandpass in cascade and CBQ structure. The analysis and simulations were performed using MATLAB and LTSpice software. After obtaining the results, a filter model was made experimentally. The correctness of its work was evaluated and confirmed by using osciloscope and a function generator. Detailed measurements were performed by using network analyser, and the validity of the calculated elements and characteristics was confirmed. This led to the conclusion that the filter works properly and it can be produced for real-life purposes
