| 摘 要： | 通过大量抽取均匀滤波器组中产生的混迭分量并对之进行分析,提出了适当设定综合滤波器与分析滤波器的关系以使混迭相互抵消的方法。理论分析表明,在频率交界点可将混迭完全消除,如果相邻滤波器的频率特性对称性较好,可使总混迭很小。实验证明该方法有效。

| Abstract: | Based on analysis of a large amount of juxtaposition components extracted from uniform filter suites,the paper proposes a method for appropriate settings of the relations between comprehensive filters and analyzing filters so that the juxtaposition is mutually cancelled.Theoretical analysis shows that juxtaposition can be totally cancelled at frequency boundaries.Good symmetricality of frequency properties in adjacent filters results in little total juxtaposition.Experiments have verified the effectiveness of the method. |
