%X The Fourier integral transform is a very useful tool for analyzing the frequency content of steady processes. When dealing with non-stationary processes, however, other methods for determining the frequency content must be applied. This paper deals with the windowed Fourier transform and, the more recent, wavelet transform. The windowed Fourier transform uses basic functions that have an unlimited definition range and requires multiplication of the observed process with a time-limited window function to be able to detect local non-stationarities. The wavelet transform uses basic functions that have a limited definition range for the same purpose.
