Abstract:

The analysis of transient signals using classical techniques is frequently not satisfactory. The Fourier analysis is based on stationarity of the signaL and transients are nonstationary. A new technique for the analysis of this type of signal, called the Wavelet Transform, was applied to artificial and real signals. A brief theoretical comparison between the Short Time Fourier Transform and the Wavelet Transform is introduced A multisolution analysis approach for implementing the transform was used. Computer code for the Discrete Wavelet Transform was implemented. Different types of wavelets to use as basis functions were evaluated. KAR P. 2
