| 摘 要： | 指出广义反馈公式K_f=K_0/(1+K_0B)实际上是节点电压关系式,和反馈一般表达式A_f=A/(1+AF)在本质上是不同的。介绍一种利用叠加定理的方法,可以在不划分框图的基础上,用一般表达式求出闭环网络的传递函数。

| Abstract: | This paper point out that the formulation K_f=K_0/(1+K_0B) is practically a voltage relation between two nodes. It differ from the popular formulation for feedback A_F=A/(1+AF) A method to utilize superposition principle is introduced. The transfer function of closed network can be found out by means of the popular formulation A_f=A/(1+AF),even if the feedback amplifier is not separated into two blocks. |
