| 摘 要： | 本文提出一种适于模拟数字混合电路故障诊断的验证方法,该方法对模拟元件和数字元件的故障特征均用故障补偿源表示;在求解诊断方程过程中,当数字元件状态预估值与实际值不相符时,不需要利用修正后的预估值重新求解诊断方程,从而减少了测后计算量,对所提方法在计算机上做了模拟,证明算法有效。

| Abstract: | A fault verification method of analog-digital hybrid circuits is proposed in this paper. The fault signatures of analog and digital components are all characterized by fault compensation sources. When the state estimation values of digital components are uncoincident with actual values, it is unnecessary to solve the diagnostic equations again with the estimation values corrected. |
