| Abstract: | As viewed from signal processing and engineering application,the often-used mathematical terms and basical concept of wavelet and wavelet transform and the time-frequence localization feature of the wavelet transformer are introduced in this paper.It shows the wavelet transform is a desired tool to analyze non-steady variable signal and gives a basis to further understand the wavelet transform and to apply it in engineering. |
