Spectral analysis of periodic signals by using the application created in MATLAB

Iveta TOMČÍKOVÁ, Martin CHOMA

The paper deals with spectral analysis of periodic signals. The line Fourier spectra of such type signals are obtained by using the application created in MATLAB environment.

The trigonometric coefficients are calculated using the symbolic calculus that is one of advantages of MATLAB. After computing the coefficients of the Fourier series expressed in the spectral form the application with graphical user interface plots corresponding line amplitude and phase spectra for given signals.
