摘要
总结、辨析了对负反馈在减少非线性失真、抑制噪声、深度负反馈受参数影响、展宽通频带等在认识上,容易出现差错的几个问题。
This text summarizes and discriminates the following problems in which mistakes may ariser easily on the understanding,such as:negative feedback at reducing nonlinear distortion and suppressing noise;profound and negative feedback under the impact of parameter can widen the passband.
