多回环反馈网络零回归比和零回归差的计算

Computation to Null Return Ratio and NullReturn Difference of Multiloop Feedback Network

本文将不定阻抗矩阵应用于多输入、多输出、多回环反馈网络的分析，并推导出利用不定阻抗矩阵的一阶、二阶代数余子式来计算多输入、多输出、多回环反馈网络的零回归比和零回归差的计算。

In the paper, indefinite impedance matrix is used for analysis of mumulti-input, multi, multi-output, and multiloop feedback network. It also providesthe formulas for computation of null return ratio and null return difference matrixin multi-input-multi-output and multiloop feedback network in terms of the firstand second order cofactors of indefinite impedance matrix.
