To conquer the problem of acquisition high effectiveness in analog circuit fault imformation, wavelet transform was researched in this paper to preprocess the fault signals. meanwhile, bp neural network diagnosis method based on wavelet transformation was proposed, this method can abstract fault feature effectively and decreases the dimension of imput vector. by this mean, the construct of neural network can be simplified and training time was economized, then the recognize ability of fault type was improved also
為解決模擬電路的故障信息高效獲取難題，本文採用小波變換作為故障信號的預處理器，研究了基於小波變換預處理的bp網路故障診斷方法，該法能在有效提取故障特徵的同時，降低輸入信息的維數，從而進一步簡化了神經網路的結構，減少了其訓練時間，提高了辨識故障類別的能力。 -
A planar sidm with j loops ( expressed in term of smj ) can be regarded as comprising of a sidm with j - loops ( expressed in term of smj - 1 ) and a dyad ( expressed in term of dyadj ). then, the circuit condition of sm, is determined by the circuit condition of smj - 1 and the configuration of dyadj. based on the above thought and combined with the automatic generation of structural decomposing of planar mechanism according to the type transformation theory, circuit automatic identification of planar sidm are realized, two examples are given to demonstrate the use of this method
具有j個環路的sidm可看作由j - 1個環路sidm與一個雙桿組（記作dyad _ j ）組成，則sm _ j的迴路情況由sm _ （ j - 1 ）的迴路情況、 dyad _ j的構形以及dyad _ j與sm _ （ j - 1 ）運動的相互作用決定，基於此思想，在全面分析了所有類型雙桿組的構形及裝配條件的基礎上，與型轉化法機構結構分解路線的自動生成相結合，實現了平面sidm迴路識別的系統化與自動化；最後給出了兩個分析實例。 -
