Multi-resolution Characteristic of Wavelet Transformation and Its Application to Electric Signal Analysis
Gang Tian · Journal of Nantong University · 2005
The paper introduced the basic theory of wavelet multi-resolution decomposition and studied its application to feature extracting and noise eliminating of electric signals.The result of simulation analysis showed that high frequency component gained fromwavelet decomposition could distinctly reflect the details of signals.Through the disposal and reconstruction of high frequency component in signals,useful features in signals could be obtained or the noise in signals could be removed.
