| 摘 要： | 在Ｍａｌｌａｔ的基础上，讨论了从连续小波变换到离散小波变换的过程，得出离散过程要受诸多因素的限制，其中信号ｆ（ｔ）的离散同样必须满足Ｎｙｑｕｉｓｔ抽样定理。

| Abstract: | The discrete processing of the continuous wavelet transforms is .discussed. The result is that when the vavelet transform be discretized, it must satisfy some condihons special Nyquist's theorem. |
