| Abstract: | A new theorem named conservation of node voltage sensitivity weight is presented and proved in this paper. Equivalence between this theorem and the theorem of conservation of node voltage change ratio sequence is clarified. According to these theorems fault dictionary method based on Node Voltage Sensitivity weight sequence is presented. By this method,it is easy to construct a fault dictionary of small size which can locate soft or hard fault in linear analog circuit. |
