Description: 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.
