| 摘 要： | 本文讨论了连续小波变换使用中应注意的问题，提出了从连续小波能量误差的角度及Ｎｙｑｕｉｓｔ条件出发选择连续小波变换的时频域窗，小波采样率及伸缩因子等参数，并给出了具体的例子加以说明，为正确应用连续小波变换提供了一种依据。

| Abstract: | This paper discusses the problem of applying CWT and presents how to chose the parameters of CWT such as width of timefrequency domian window,sampling interval and scaling factor based on both energy error of continuous wavelet and Nyquist criterion,meanwhile,we also show examples to account for these.It provides basis for correctly applying CWT. |
