【简答题】
某放大电路由两级参数相同的负反馈放大电路组成，如下图所示。已知每一级的基本放大电路的放大倍数[mathjaxinline]dot {A_1}[/mathjaxinline]=[mathjaxinline]dot {A_2}[/mathjaxinline]=100,反馈系数数[mathjaxinline]dot {F_1}[/mathjaxinline]=[mathjaxinline]dot {F_2}[/mathjaxinline]=0.09。设级间的相互影响可忽略不计。则该放大电路的放大倍数[mathjaxinline]dot {A_{ m f}}[/mathjaxinline]=[mathjaxinline]frac{dot {X_{ m 0}}}{dot {X_{ m i}}}[/mathjaxinline]_____。
