模拟电路的模块级故障诊断

本文以多端口元件或子网络为基本单元，提出了一种模块级故障诊断方案，这种方案的故障模型更符合电路的实际情况，因而具有更广泛的实际意义，文中首先推导了模块故障诊断议程，并对模块故障可测性问题进行了一般性讨论。然后，给出了模块故障可测的几个拓扑条件，并通过定义广义独立通路使这些拓扑条件适用于一般的非互易网络。

The Module Level Fault Diagnosis of Analog Circuits

In this paper, a module level diagnostic method is presented which considers multi-port device or sub-network as the basic unit. The fault model of this method is closer to the actual conditions, hence it has more comprehensive and practical meaning. First, the equations of module level fault diagnosis are derived ,and the testability problem for module fault is discussed in general. And the paper gives several topological conditions for module fault testability, which are applicable to general nonreciprocal network by defining the generalized independent path.
