摘要
本文借助数学方法及计算机分析手段,对基带传输中的群时延特性及其对信号传输的影响进行了分析,从中找出了群时延失真与信号波形及传输速率之间的定量关系,提供了一种分析群时延特性的手段和依据。
In this paper using mathematics and computer analysis, we analyze the effect of group delay characteristic on signal transmission in baseband transmission, find quantitative relations among group delay, signal waveform and transmission rate, provide a method and foundation of analyzing group delay characteristic.
