High source and load reflections require a long time for multiple reflections to decay.
高度不匹配之电源与负载抗，传输线上多重反射之衰减时间很长。
A simple and flexible signal source of multiple decay was designed with the linear adding of many rc charging signals.
用多个RC充电过程信号的线性叠加设计了一个复杂衰减过程的信号源，简单而且具有灵活性。
Mainly used three methods, including including the F-K domain filter, internal excision and the energy decay method to attenuate multiple and obtained a more ideal result.
主要采用了F - K域滤波法、内切除和近道能量衰减法压制多次波三种技术，取得了较好的效果。
