摘要
基于正余弦变换是汉克尔变换的特例 ,运用成熟的快速汉克尔变换理论 ,导出了正余弦变换的数值滤波算法 ,并给出了各 2 5 0个滤波系数。以有解析解的李普希兹积分为例 ,与现有的算法作了试算对比 ,证明该算法的计算精度高 。
Based on the sine and cosine transform which is the special case of the Hankel transform, applying the mature theory of the fast Hankel transform, this paper derived the digital flit each. An numerical er algorithm of the sine and cosine transform and gave 250 filter coefficients for example of calculating Lipschitz integral which can be calculated by analysis results show that this algorithm can give high precision and is suitable for s ding its use. the preading its use.
