Banco de filtros Wavelets com fator de escala maior que dois
(Universidade Federal de Minas GeraisUFMG, 2007-03-20)
The traditional wavelet analysis is equivalent to a filter bank, formed by a low-pass and a high-pass filter, in which the frequency resolution changes by one octave between two subsequent stages. In some applications, ...
Approximations of the inverse wavelet transform for analogue circuits
(2012)
We propose two approximations of the inverse wavelet transform implemented with a voltage adder and two analog filters. They work together with a set of scaled band-pass analog filters that perform the wavelet transform ...

Processamento de sinais de descargas parciais em tempo real com base em wavelets e seleção de coeficientes adaptativa espacialmente
(Universidade Federal de Minas GeraisUFMG, 2011-11-04)
On-line partial discharge (PD) analysis is a highly pursued feature due to the economy related to scheduled shutdowns, disassembling and transport. Nevertheless, on-site PD measurements are frequently limited by interferences ...
