| Abstract: | In this paper, the idea and the property of the S-transform are presented, and non-stationary time series is synthesized, four time frequency methods are compared. The results show that the S-transform has high time and frequency resolution. In the last part of the paper, some application examples of time-frequency analysis are enumerated. It confirms that time-frequency analysis has extremely wide application perspectives. |
