摘要
小波理论在最近几年发展极其迅速，它在不同领域中已取得了成功的应用．本文讨论小波和小波变换的性质，并借以小波理论是局部分析的有力工具，对一小段上医学信号的异常信息，可以很灵敏地通过小波系数反映出来．在医学信号处理中小波理论还能够被用作多功能滤波器．
Wavelet theory bevelopes very fast in the past few years．It has been applies successfully in many areas．In this paper，the authors first discuss the basic properties of wavelet and wavelet transform．From the discuss it can be seen that wavelet theory is a strong tool in the local analysis.For a piece of medical signal the abnormal infoumation can be effectively detected from the its wavelet coefficients.The wavelet theory can also be used as a multifunction filter in the medical signal processing．
