再生中继是从英语Regenerative Repeater翻译的,它是PCM和TDM所需要的.它与模拟信号FDM的线性增音显然不同.再生中继的作用是:数字信号脉冲受到衰耗、色散和噪声的影响,到达一定距离,需要中继站来帮忙,这中继站只须辨认有没有传来信号,如果认出信号,就再生一个新的信号,发往下一段线路.这个新信号的幅度、宽度和形状,与前一段线 The regenerative relay is translated from the English Regenerative Repeater, which is required for both PCM and TDM and is clearly different from the linear gain of the analog signal FDM. The regenerative relay acts as a digital signal whose pulses are attenuated, chromatic and noisy Influence, to reach a certain distance, need a relay station to help, this relay station only need to identify whether there is a signal, if you recognize the signal, to regenerate a new signal sent to the next section of the line. The new signal amplitude, width and shape, With the previous paragraph of line
