Description: 这就相当于透过栅栏观赏风景,只能看到频谱的一部分,而其它频率点看不见,因此很可能使一部分有用的频率成分被漏掉,此种现象被称为栅栏效应。
不管是时域采样还是频域采样，都有相应的栅栏效应。只是当时域采样满足采样定理时，栅栏效应不会有什么影响。而频域采样的栅栏效应则影响很大，“挡住”或丢失的频率成分有可能是重要的或具有特征的成分，使信号处理失去意义。
-This quite in penetrates the stockade watching scenery, can only see the frequency spectrum a part, but other frequency spot cannot see, therefore very possibly causes a part of useful frequency component to leave out, this kind of phenomenon is called the stockade effect.no matter is the time domain sampling or the frequency range sampling, has the corresponding stockade effect. Is only when the time domain sampling satisfies the sampling theorem, the stockade effect will not have any influence. But the frequency range sampling s stockade effect affects is very big, “blocks” either the loss frequency component has the possibility is important or has the characteristic ingredient, causes the signal processing to dwindle.
