Bode图及其特点

方便绘图

在初步分析（或综合）时，可用分段的直线（渐近线）来近似表示对数幅频特性（曲线），易于绘制和修改。若需要，再对渐近对数频率特性曲线进行修正，则可得较准确的曲线。

-Bode diagram of the characteristics of the drawing to facilitate an initial analysis of (or integrated), the available sub-line (asymptote) to express approximate logarithmic amplitude-frequency characteristic (curve), easy to draw and modify. If necessary, further to the asymptotic logarithmic frequency characteristic curve of an amendment may be a more accurate curve.
