在线性运放电路中应用直观性计算法

The Application of Visual Calculation to the Linea Operational Amplifier Network

在含运算放大器的线性网络中,利用网络信流图的概念和梅逊增益公式,直接列写线性网络的传递函数,特别是选取高阶项和丢弃低阶项的作法,使计算简化,这给工程应用带来很大的方便。

The basic concept of signal flow graphs and the Mason's gain formula are employed to calculate transfer functions directly. In order to make the calculation simpler, higher order term can be selected and lower order term thrown out in the linear operational amplifier network. It is very con-venient to use this method in engineering.
