related interpolator

The interpolation precision of pulse multiplier-based fine interpolator is related with the max feed rate, pulse equivalent of CNC, interpolation cycle, and output pulse frequency of pulse generator and the main reason of its error production comes from the rounding processing of crossover frequency number.

基于脉冲乘法器原理的精插补器的插补精度与最大进给速度、机床系统的脉冲当量、插补周期以及脉冲发生器的输出脉冲频率有关，其误差产生的主要原因是由分频数圆整造成的。

Lastly, it researchs a new efficient Interpolator and introduces a new anti-aliasing digital filter technical which is not related to interpolation timing adjustment but has some new ideals in it.

最后是高效的内插技术研究以及和内插定时调整无直接关系但对数字上下变频的抗混叠滤波技术有所改进的抗混叠数字滤波技术。
