噪音抑制方案示例
EXAMPLES  OF  NOISE  COUNTER  MEASURE
目标Target
a.抑制IC电源线上的噪音,消除电源线上的噪
音,稳定IC的工作电压。
Restrains  and  eliminates  the  noise  of  
the  IC  power  supply  line  and  make
the  voltage  of  IC to  be  stable.
b.抑制信号线上的幅射噪音:衰耗信号中多余
的高频成分,阻止噪音的幅射。
Restrain the radiation noise of the signal 
lines. Wane  the  extra  high  frequency
to  prevent  noise  radiation.
