摘要: An apparatus and a method for adaptive time-frequency analysis are suitable nonlinear nonstationary signal analyses. The includes the following steps. A plurality of positions local extrema is determined. Average frequencies between mean energy distribution corresponding thereto estimated according to signal. instantaneous determined by way optimization each extrema. Finally, an frequency
