摘要: 在使用K故障診斷法時(shí),為提高電路的可診斷性,可以采取諸如增加可及節(jié)點(diǎn),或改變激勵(lì)點(diǎn),增加激勵(lì)和測(cè)量次數(shù)等辦法。本文對(duì)這些措施的有效性,以及如何增加可及節(jié)點(diǎn)問題進(jìn)行了詳細(xì)的討論,特別著重對(duì)比較有效的多激勵(lì)法進(jìn)行研究,給出了用多激勵(lì)法進(jìn)行診斷時(shí),電路可K故障支路診斷的條件。

Abstract: In view of K-fault testability, the topological construction of a practical circuif is far from ideal. In order to improve the testability of a circuit, it is used to increase the number of accessible nodes or to use multi-excitation method. Effectiveness of these methods and feasibility choosing accessible nodes arc discussed in detail. The conditions for multi-excitation testability are presented. -
