Digital filters are very often building blocks of microelectronic circuits. They belong to the group of potentially chaotic circuits. In this paper discuss the danger of chaos in a second-order digital filter. With the computer simulation program (Matlab) we analysed the behaviour of linear and non-linear 16-bit model. We found that the chaotic behaviour is impossible in the linear model. In order to exhibit chaotic behaviour, a digital filter has to be at least of 16-bit structure andno signals must be present on input, and filter's coefficient must guarantee that filter operates on the boundary of the stable region. The chaotic digital can be used as a generator of chaotic sequences that are needed in the cryptographic systems"},{"@xml:lang":"sl","#text":"Nekateri digitalni sistemi se lahko v določenih razmerah začnejo obnašati kaotično, kar lahko privede do začasne odpovedi sistema. V skupino kaotično potencialnih vezij spadajo tudi digitalna sita, ki so sestavni del mnogih mikroelektronskih vezij. V prispevku obravnavamo nevarnost kaotičnega obnašanja digitalnega sita drugega reda. Z računalniško simulacijo (programski paket Matlab) smo analizirali obnašanje linearnega in 16-bitnega nelinearnega modela. Ugotovili smo, da se linearni model nikakor ne more obnašati kaotično. Nujna, vendar ne edina pogoja za kaotičnost sta: 1. struktura sita mora biti vsaj 16-bitna, 2. na vhodu ni prisoten noben signal. Kaotičnost je pogojena tudi z ustreznim izborom začetnih stanj in vrednosti koeficientov, ki zagotavljajo, da sito deluje na robu stabilnega območja. Kaotično digitalno sito je možno tudi koristno uporabiti kot generator psevdokaotičnih sekvenc, ki ga potrebujemo pri razvoju čipov na področju kriptografskih sistemov"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-REREADM1","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-REREADM1"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-REREADM1/2907d30b-2ac5-41bc-8757-f44b8e4e7783/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Strokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-REREADM1/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-REREADM1"}}}}
