The classical method for the digital Butterworth filter design is to work out corresponding analog filter first,then obtain the digital Butterworth filter from the bilinear transform,therefore the traditional method relies on the analog filter,and cannot obtain the zeros-poles plot equal filter.
设计数字式巴特沃斯滤波器的传统方法是先设计好相应的模拟滤波器,再经过双线性变换得到数字式巴特沃斯滤波器,因此必须依赖于模拟滤波器,同时无法得到零极点数量不相等的滤波器。
2.
In order to make the digital filter to maintain the frequency characteristic of the original analog filter,a expression for the prewarping is derived according to the definition of the bilinear transform,and a low-pass Butterworth digital filter is designed.
并利用该式设计了一个低通巴特沃斯数字滤波器分别对三种情况(双线性变换、提出的预畸变方法和模拟滤波器)的幅度响应进行了计算机模拟。
3.
Here, Butterworth-respond method is adopted to approach ideal characteristic, and the rank order of the filter showed to be the main factor that influences a low-pass filter accuracy.
介绍了如何由物理不可实现的理想低通滤波器到实际可实现的数值模拟滤波器的具体过程,具体采用了巴特沃斯响应逼近理想特性,并说明了滤波器的阶次是影响低通滤波器精度的主要因素,最后结合实例,借助MATLAB进行了模拟低通滤波器的设计仿真。
