摘要
具有反馈的放大器,当考虑负载效应时,其分析过程相当繁琐。本文应用二端口网络理论和信号流图,对具有负载效应的四种基本反馈形式进行了讨论,并概括成个统一的信号流图和一套通用的计算公式,从而使分析过程简化。
The analyzing process of feedback amplifier, when considered with load effect, is quite complicated and tedious.The paper has discussed four basic feedback modes of load effect, in which the two port network theory and signal flow graph are applied.A unified signal flow graph and a set of general calculating formulas have been generalized in the paper, thus the analyzing process is simplified.
