Abstract

U radu je detaljno analiziran način rada četverokanalnog audio miješala po funkcijskim blokovima. Analiziran je i izmjeren frekvencijski odziv tropojasnog ekvilizatora s dodatnim visokopropusnim filtrom. Opisan je način rada window komparatora, i dizajnirano je transimpedancijsko miješalo signala. Izrađene su sheme uređaja i dizajnirane tiskane pločice, te su za uređaj izabrane komponente s naglaskom na cijenu i jednostavnost izrade i korištenja. Uređaj je složen u malo plastično kućište s ciljem lake prenosivosti i jednostavnog korištenja. Mjerenja koja su obavljena na uređaju pokazuju njegovu funkcionalnost i točnost izračuna pri dizajniranju sklopa.

Abstract (english)

The paper analyzes in detail the mode of operation of the four-channel audio mixer by functional blocks. The frequency response of the three-band equalizer with an additional high-pass filter was analyzed and measured. The mode of operation of the window comparator is described, and a transimpedance signal mixer is designed. Schemes of the device were created and printed circuit boards were designed, and components were chosen for the device with an emphasis on price and ease of manufacture and use. The device is folded into a small plastic case with the aim of easy portability and simple use. The measurements made on the device show its functionality and the accuracy of the calculations when designing the circuit.
