The block diagram method is widely used to analyze the negative feedback amplifier at present.
目前，方框图法是被广泛使用的分析负反馈放大电路的方法。
In this paper, two methods of analysis, the block diagram method and the equivalent circuit method, have been introduced simultaneously with specific examples of three negative feedback types.
本文通过三种负反馈类型的具体例子同时介绍了两种分析方法，即方框图法和等效电路法。
