While working on a means of reducing amplifierdistortion, he devised the negative feedback amplifier.
在研究减少放大器失真方法时他发明了负反馈放大器。

Amplifierdistortion produces a dilation of the spectrum of the input signal (" spectral regrowth ") which causes interference to communications in adjacent channels.
放大器失真引起输入信号的频谱再生，这对相邻信道中的通信产生了干扰。

A high power filter (38) is located downstream of the power amplifier (20) and causes linear distortion.
