DIGITAL FILTER ALGORITHM OF THE SINE AND COSINE TRANSFORM

WANG Hua-jun (Information Science & Engineering College, Huaqiao University, Quanzhou Fujian 362011, China)  
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 filter algorithm of the sine and cosine transform and gave 250 filter coefficients for each. An example of calculating Lipschitz integral which can be calculated by analysis, the numerical results show that this algorithm can give high precision and is suitable for spreading its use.
