| 摘 要： | 信号辅入最大电路后，由于放大电路中存在非线性元件和线性电抗元件，使输出信号失真。对阻容耦合放大器而言，当放大电路引入负反馈后，只能改善非线性失真，及线性失真中的幅度失真，不能改善线性失真中的相位失真等。负反馈展宽了最大电路的通频带，但不等于改善了频率失真。

| Abstract: | Signal having input arnplifier electric circuit, output signal is made distortional by the nonlinear components and linear reactance components existing in amplifier eletric circuit. As fOr RC-Coupled amplifier, negative feedback can ameliorate only nonlinear distortion and the range distortion in lineax distortion, but can' t ameliorate phase distortion in linear distortion. Negative feedback widened the pass band of amplifier electric circuit, but this dOesn' t mean ameliorating frequency distortion |
