Real time spectrum analyzer light

Abstract: The purpose of this study was to analyze the experimental level spectrum in real time. The first step of this study was the acquisition of signal over the function generator (Hp Hewlett Packard) and viewing the same through the oscilloscope (Agilent). In this thesis, MATLAB was used as a tool. The whole process of the signal Fourier transform was made with this process and the values were put in a matrix, making it possible to obtain the amplitude values and to observe them through a three-dimensional graphic.
