摘　　要：用信号流图计算反馈放大器的输入输出阻抗，并进一步明确在分析反馈放大器不同指标时，所采用的反馈深度的具体含义。The signal flowing graph is used to calculate the impedances both for input and output from the feed back amplifier. This method presents a clear definition of the meaning about feed back depth having been used when all different indexes are being analyzed.

关 键 词：反馈放大器 信号流图 输入阻抗 输出阻抗
