摘要

提出了对Remez算法的改进，以获得用于非递归数字滤波器合成的模拟原型传输系数的最佳均匀逼近。原型传输系数在阻带区域具有指定数量的传输零。利用二阶相位校正器减小了群延迟时间的变化。

Synthesis of digital filter characteristics as a part of program FCAD-96 for filters synthesis

The modification of algorithm of Remez for the best uniform approximation of analog prototype transmission coefficients used in synthesis of none-recursive digital filters is proposed. The prototype transmission coefficient has a specified number of transmission zeroes in stop band region. Variations of the group delay time were reduced with the help of the phase corrector of the 2nd order.
