摘要
针对Butterworth低通滤波器归一化后的传递函数动态性能指标的单一化,提出了可以根据需要改变其动态性能指标的低通滤波器。基于牛顿迭代法对Butterworth低通滤波器的极点的位置进行迭代计算,使重新分布极点的滤波器的传递函数动态性能指标满足设备的需求,并对改进后的低通滤波器进行阶跃响应分析。
The dynamic performance indicators of the transfer function for Butterworth low-pass filter is a single,so this paper presents a low-pass filter which can change the dynamic performance indicators.The pole of Butterworth low-pass filter is re-distributed with Newton iteration,so that the dynamic performance indicators could be in accord with the demand for equipment,and carried on the step response analysis for improvement low-pass filter.
