The tests used the discrete wavelet transform (DWT) and distinct noise levels to contaminate the base signals in search for the most suitable wavelet basis to denoise. As a performance criterion, the energy of the difference between the source signal and the filtered one was usedAttribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/DOASAnálise de desempenho de waveletRemoção de ruídoWaveletarticle10.15628/holos.2015.2127
