求翻译：由所学可知，正交小波变换可以把信号的频谱分解到不同的频率范围，并且正交变换具有去除信号中的相关性和信号能量集中的功能，因此通过小波变换把信号的能量集中到某些频带的少数系数上。这样通过将其他的频带上的小波系数置零或给予小的权重，即可达到有效抑制噪声的效果。是什么意思？

Known by the learned, the orthogonal wavelet transform the signal spectrum can be decomposed into different frequency ranges, and the orthogonal transformation with the removal of the signal and the correlation function of the signal energy concentration, the wavelet transform to concentrate signal

It can be seen by the students, orthogonal wavelet transform can be cascaded down to the signal frequency spectrum of different frequency range, and orthogonal transforms a signal to remove the relevance of the energy and signal the functionality, and therefore focus on wavelet transform the signal

By what they have learned, orthogonal Wavelet transform decomposition to a different frequency range of the frequency spectrum and orthogonal transformation and removal of signal correlation between signal energy concentration of functions, so signal through Wavelet transform energy focused on the f

Learn can know little wave orthogonal may decompose the frequency spectrum of the signal to different frequency scopes to vary, and the perpendicularity varies and removes the function that relevance and signal energy concentrate in signals, so vary and concentrate the energy of the signal on a few
