Abstract
U ovom završnom radu pomoću Arduino platforme, LED zaslona i mikrofonskog pojačala izrađen je frekvencijski analizator signala. Ulazni analogni audio signal koji dolazi sa mikrofonskog pojačala Arduino uzrokuje i pretvara u digitalni te sprema kao diskretan niz vrijednosti tog signala. Zatim se taj signal pretvara korištenjem FFT biblioteke u frekvencijski spektar. Takav transformirani signal se skalira i prilagođuje kako bi se na LED zaslonu prikazala energija pojedinih frekvencijskih pojaseva u signalu.
Abstract (english)
In this bachelor thesis, a frequency signal analyzer has been designed using the Arduino platform, an LED display and a microphone amplifier. The input analog audio signal coming from the microphone amplifier is sampled by the Arduino and converted to a digital value and stored as a discrete array. Then the signal is converted using the FFT library into its frequency spectrum. This transformed signal is then scaled and adjusted in order to be displayed on the LED screen as energies of the individual signal frequency bands.
