应用撕裂法诊断模拟电路单支路故障

Application of Tearing Method to Single-Branch-Fault Diagonsis of Anolog Circuits

撕裂法对于模拟电路的故障诊断是一种有效的方法．本文在文［１］的基础上更深一步地研究了 撕裂法应用于单支路故障诊断时选择检验变量的依据，给出了单支路可诊断的拓扑条件，进而完成了 对网络单支路故障的定位定值计算．

Tearing method is effective in fault daignosis of anolog circuits. In this paper, the results of a further study of reference [1] is presented, and the rules for determinig the check variable and the topological conditions for single-branch diagnosibility are provided. An ex- ample for the location of fault and the calculation of its value are given.
