| 摘 要： | 在模拟电路中，任何一个元件值偏差与一个端口电压或电流之间存在Ｍｏｂｉｕｓ变换关系，对故障分析很有帮助。本文在讨论这一变换后，证明了纯阻网络偏差元件下的电流电压变化最大。再将端口响应变化与元件偏差值之间的关系在扩充复平面上直观地全面概括在一幅圆网之中。

| Abstract: | in analog circuits,there exists Mobius transformation between the deviation of any element parameter and the change in response at a port.This is helpful to fault analysis.In this paper,following the discussion of this transformation,maximal change in voltage and current of the fault#element in resistive networks is proved.Then the relationship between the change in response and the deviation of element parameter is fully described by a circlenet on the extended complex plane.Finally an algorithm for single-fault diagnosis is introduced as its application. |
