摘要
小波分析里，起关键作用的是共轭滤波器。本文证明了Ｄａｕｂｅｃｈｉｅｓ的｜ＨＮ（ω）｜２与Ｍｅｙｅｒ的｜ＨＮ（ω）｜２有相同的极限。并根据其极限给出了一种新的滤波器Ｈ（ω），证明了Ｎψ（ω）几乎处处收敛于ψ（ω）。
In wavelets analysis,a crucial role is played by filter. In this paper,we prove tha | HN(ω) |2 introcltlced by I Daubechies in 1988 and | HN (ω )|2 introduced by Y Meyer have the same limit. A new filter H(ω) based on the limit is shown and and Nψ→ψ(ω) is proved.
