| Authors: | Xu Mingtao Tang Baoping |
| Abstract: | Sampling principle and characteristics and edge effect of orthogonal wavelet transform of signals are researched. Two samples of signals and wavelet bases must be taken in wavelet transform. In the second sample sampling interval or sampling length in different frequency range will be automatically adjusted. Wavelet transform can detect singular points. Both ends of signals are singular points. Edge effect is not avoidable. |
| Keywords: | Signal Sample Wavelet transform Localization Edge effect |
