The traditional method for amplitude-phasefrequencycharacteristic calculation is first to solve the numerator polynomials and denominator polynomials of a transfer function.
频域计算的传统方法是先求出传递函数的分子多项式和分母多项式。

It can measure the magnitude characteristic, phasecharacteristic and limiting frequency of a system.
它能直观的测试一个系统的幅频特性、相频特性和截止频率。
