1. teach yesterday rules apply, we can design a system.
2. as shown in the figure, the ideal operational amplifier characteristics, can be used to simplify analysis.
1.應用昨天教的規則,我們可以設計一個系統。
Using yesterday Catholicism's rule, we might design a system.
2.如圖所示,運算放大器的理想特性,可以被用於簡化分析。Like the chart shows, operational amplifier's idealized characteristic, may use in simplifying the analysis.
