  1. Taking dc motor test as an example, a creative idea of applications of some advanced signal processing tools, such as time - frequency analysis, wavelet, and instantaneous frequency ( if ) evaluation, in motor testing field is presented. the paper systematically summarizes basic theories of time - frequency analysis and wavelet transform based on which an in - depth research of effective if evaluation based on wavelet ridge and wavelet curve is carried out. in the end a fast t - n characteristic testing system with neither torque nor speed sensor is successfully developed

    本論文主要關注小波分析在電機性能自動測試系統中的應用，針對傳統電機測試系統以及信號處理技術在電機測試領域中應用的不足，以直流電機為例，提出了將時頻分析、小波包變換以及基於小波脊的瞬時頻率提取方法應用到電機測試領域的新思路；較系統地總結了時頻分析和小波變換的基本理論，深入探討了基於小波脊線和小波曲線的瞬時頻率提取，並成功開發了基於正交小波包分析和基於小波脊線的瞬時頻率提取的無轉矩轉速傳感器的直流電機快速測試系統。
  2. For those biological signals like echo of bat or whale, as well as man - made system signals like radar or sonar signal, the instantaneous frequency of signal component contains important information and could be used for signal model parameters extraction. so that the proper choose of transformed domain and signal characteristic extraction method is of crucial important. the ridge extraction method used for signal characterization was first proposed in the 1990s, it ' s based on the study of the phase of the wavelet ( or other linear ) transform

    對于許多實際的信號，如蝙蝠發出的超聲波、鯨魚的叫聲等生物信號，以及雷達、聲吶等人造系統產生的信號而言，信號瞬時頻率的變化規律反映了信號重要的特徵，並且也是信號模型中關鍵的參數，因此選擇合適的變換域提取信號的瞬時頻率信息，並選擇合適的方法對信號進行重建是很重要的問題。
