在长线传输中各种不同频率的信号衰减量是不一样的,频率越高衰减越大,这就产生了所谓的频率失真。图1曲线①是双铁线传输线频率特性的理论曲线。此传输线的长度为25
In the long-term transmission of different frequencies of signal attenuation is not the same, the higher the frequency the greater the attenuation, which resulted in the so-called frequency distortion. Figure 1 Curve ① is the theoretical curve of the frequency characteristics of double wire transmission line. The length of this transmission line is 25
