Abstract

Spectral analysis of functions obtained experimentally by three different methods is carried out. The methods are discrete Fourier transform (DFT), improved DFT, and a new method based on the classical Fourier analysis method. The analyzed waveforms are observed once as a sequence of samples (theoretical representation), and once as a sample and hold function (physical representation). The main points of the analysis are: calculation of the spectra using the different methods; obtaining approximated functions by the summation of the derived harmonics; and estimation of the errors in the approximation
