针对“电压串联负反馈对输入电阻的影响”实验中出现的测试结果和理论分析不一致的问题,讨论了相关理论存在的条件,给出了实验电路转化为此条件下有关输入电阻的结论,并通过测试结果进行验证。
In allusion to the inconsistent test results and theoretical analysis in the experiment of “the effect of voltage series negative feedback on input resistance”, the existing conditions of the relevant theory are discussed and the conclusion that the experimental circuit transforms to the input resistance under this condition is given. Through the test results to verify.
