摘要
就一类保持正交性且具有一定逼近阶的预滤波方法作了详细的讨论,给出了具体设计方法和设计实例.用此类预滤波方法构造的预滤波器保持正交性且运算方便,此方法有较大的实用价值.
A class of prefilter based on approximation order and orthogonality was described in detail, and the construction of this prefiher was given in this paper. The prefiher constructed in this way satisfies orthogonal relation and the operation is convenient. The method presented is greatly valuable in application.
