摘要
微波信号的长距离传送中 ,信号常常失真 ,采用数字中继再生 ,可对脉冲进行变化整形的过程中只对信号放大 ,对噪声加以抑制 ,消除了失真和噪声的累积效应 。
When signal is conveyed in a long distance, The sigal is often deformed. So we must magnify the valid signal while weaken the invalid signal. and the valid signal can be coveyed without deformed in a long distance. This is called regain the valid signal.
