Abstract

The theoretical bases of the Fourier and wavelet transforms are considered, the main advantages and disadvantages of the Fourier series and wavelet functions are mentioned using the program MATLAB R2013a, the analysis of one-dimensional signals in the command mode are realized, the results of investigations of the wavelet and Fourier spectrograms are presented.
