摘要
This paper show a comparative study between Discrete Fourier Transform, Discrete Wavelet Transform and Fast Fourier Transform. The math formalizations and some features of algorithms are showed and asymptotic complexity concepts. Finally, is performed a practical experiment for comparing algorithms, covering issues as executing time, pros and cons of each transformed, as well as evaluate about the diferent resolutions time/frequence of each algorithm..
