Abstract

Napisani rad opisuje detaljan postupak projektiranja, simulacije i ispitivanja
oktavnog, osam-kanalnog grafičkog korektora s digitalnim upravljačkim krugom.
Uređaj u pitanju mora biti u mogućnosti pružati kontrolu nad svim aspektima
obrađivanog audio signala – od podešavanja ulazne i izlazne razine signala,
detekcije preopterećenja sklopa, preko digitalne kontrole pojačanja kanala
korektorskog bloka pa sve do mogućnosti memoriranja korisničkih postavki i brzog
poziva istih u željenom trenutku. Realizirani uređaj mora imati robusno kućište s
nožnim kontrolara zbog uporabe u koncertnim situacijama. Dan je i uvid u kreaciju
i mogućnosti glavnog programa mikrokontrolera koji upravlja cjelokupnim grafičkim
korektorom.

Abstract (english)

The written work describes, in great detail, the design, simulation and
examination process of an 8-channel octave graphic equalizer with a digital
controller. The device in question must be able to offer control over all parameters
of the audio signal – from input and output signal level adjustment and overload
detection to digital equalizer band-gain control, possibility of user preset storage
and quick preset recall in any given moment. The device will be used in live
concert situations and must have a robust casing with foot controlled switches and
buttons. The creation and possibilities of the main microcontroller program code
are also explained.
