Abstract

U ovom radu analizirana je obrada audiosignala pri snimanju, prijenosu i reprodukciji. Prilikom prijenosa audio signala potrebno je obratiti pažnju na kapacitet prijenosnih sustava. Sažimanje podataka može se vršiti kao sažimanje s gubicima i bez gubitaka. Pomoću psihoakustički svojstava uha postiže se sažimanje audio signala odbacivanjem nečujnih dijelova signala. Mediji za pohranu podatka, omogućuju veliki kapacitet za pohranu audio signala. Putem ATM tehnologije omogućva se prijenos audio signala putem telekomunikacijskih mreža. DAB sustav je omogućio visoko kvalitetan prijenos digitalnog signala.

Abstract (english)

In this project it has been analysed audio signal proces trough recording's,transfer and reproduction. During the transmission of audio signal it's necessary to pay attention to capacity of transsmiting system's. Summarizing informations can be done as summarizing with losses or without them. With help of psycho acustic properties of human hearing it's accomplished summarizing audio signal by rejecting inaudible part's of signal. The medium for store informations are making big capacity to store audio signal. Trough ATM technology the transfer of audio signal trough telecommunications net has been enabled. DAB system has enabled high quality transfer of digital signal.
