通过计算导出了平均假频衰减与滤波器阶次及采样率的关系式。
A relation between average alias attenuation and filter order and sampling rate is derived from calculation.
根据系统的动态数学模型和动态补偿要求，便可设计这种滤波器，并可估计它的阶次和参数。
The filter can he designed and its order and parameters can be estimated according to the dynamic mathematical model of system and the dynamic compensated requirements.
另外，理想滤波器组的延迟应该和滤波器组的阶次相等。
Besides, we consider the ideal filter group's delay may be equal to it's order.
