| Abstract: | 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. |

| Keywords: | signal regain long distance covey |
