Abstract
U radu je bilo potrebno objasniti osnovne značajke pojačala i bitne pojmove koji se vežu uz njih, kao i načine podjela pojačala u različite klase na temelju njihova načina rada. Nadalje, bilo je potrebno objasniti glavne razlike između tranzistorskih i cijevnih pojačala na način da se ne oslanja na subjektivnost slušatelja već na mjerljive podatke kao što su izobličenja signala različitih tehnologija pri određenim pojačanjima. Nešto detaljnije je objašnjena i cijevna tehnologija, odnosno osnove termoelektronske emisije i način rada trioda. Krajnji cilj završnog rada bio je implementirati cijevno pojačalo koristeći ECC82 dvostruku triodu proizvođača JJ Electronic. Nakon implementacije, laboratorijskim mjerenjima utvrđeno je da je dobiveno pojačalo zadovoljavajućeg pojačanja kao i iznimno ravne frekvencijske karakteristike. Izobličenja pojačala primijećena su tek pri ulaznim naponima koja svakako nisu namijenjena za pojačalo ovakve namijene.
Abstract (english)
The paper aimed to explain the essential characteristics of an amplifier and important terms connected to them, as well as the classification of amplifiers based on their working principles. It was also necessary to explain the main difference between transistor and tube amplifiers in a way that doesn't rely on the subjectivity of the listener but rather on measurable data like signal distortion with different gains. Tube technology was also explained in more detail with thermionic emission and basic working principles of a triode. The end goal of the paper was to implement a tube amplifier using an ECC82 double triode manufactured by JJ Electronic. After the implementation, lab measurements showed good signal gain and flat frequency response results. However, signal distortion was also noticed with input amplitudes that exceed the amplitudes meant for this kind of amplifier.
