In term of this theory, we decompose some simulate signal and pipeline mfl signal by wavelet package transform. then select the best wavelet package base out of the decomposed coefficient and figure the brickwork of the best base on the relevant position in time - frequency plane showing the strong or weak of every coefficient. as a result, the time - frequency structure of signal analyzed is relatively visually represented ; that is to say, an anticipative result achieves
按照這一理論，我們對一些模擬信號和管道漏磁信號作了小波包分解，然後從中選出最優小波包基，再把被選中的小波包基的相應砌塊表示在時?頻相平面上的相應位置上，並用灰度級別表示這個分量權重的強弱，結果較形象地把被分析信號的時?頻結構表現出來，達到了預期的目的。 -
