Guitar audio amplifier

U ovom radu je bilo potrebno izraditi gitarsko pojačalo uz pomoć tranzistorske tehnologije. Odabrana je AB klasa rada zbog najprihvatljivijeg kompromisa izmeĎu kvalitete zvuka i izlazne snage. Pojačalo je rasporeĎeno na tri PCB pločice koje su raĎene tehnikom zvanom nagrizanje (eng. Etching). Distorzijometrom i osciloscopom su izmjerene dobivene vrijednosti i vidljivo je da pojačalo ima jako dobar prijenos signala odnosno jako malu distorziju, što je odlika visoko kvalitetnih pojačala.The guitar amplifier, with the help of the transistor technology, was required to be built in this final thesis. AB class was chosen because of the most appealing compromise between the quality and the power of sound. The amplifier is distributed on three PCB boards which are made with a technic called ethcing. With the help of an distorsiometer and an osciloscope the values were measured. It is clear that the amplifier has a very good signal transmission and very small ammount of distorsion, which is a quality of a high end amplifiers
