摘要
提出了利用电缆调制传递函数(MTF)方法进行频谱补偿。并作了理论分析和求解,是一种较好的信号传输失真的补偿方法。
It is nonnegligible that attenuation of signal tested in transmission cable results in signal distortion especially .in long transmission cable, the signal distortion have to be compensated. In general High frequency method can be used for compensation,but this compensation effect is not ideal according to experience. This paper describes a method on modulation transfer function (MTF) of cable used for frequency spectrum compensation and gives theoretical analysis and evaluatin. It has been demonstrated that the method is ideal for compensating signal distortion.
