- 幅值条件： [...]
- 相角条件：\(\begin{gathered}\sum_{j=1}^m \angle\left(s-z_j\right)-\sum_{i=1}^n \angle\left(s-p_i\right)=(2 k+1) \pi \\k=0, \pm 1, \pm 2, \cdots\end{gathered}\)
- 幅值条件：\(\displaystyle K^*= \frac{\displaystyle\prod_{i=1}^n\left|s-p_i\right|}{\displaystyle \prod_{j=1}^m\left|s-z_j\right|}\)
