摘要
巴特沃思滤波器(Butter-worth filter)也称为瓦格纳滤波器(Wagner filter),以其通带衰减特性平坦而闻名,由于它设计简单,性能优越而得到广泛应用。在实际设计和应用过程中,为便于分析,减小计算误差,一般采用归一化计算方法。
The Butterworth filter,which is also called Wagner filter,is well known for its flat attenuation characteristic. It is widely used because of its simple design and superior performance. The normalization method is always used in the actual design and application process in order to facilitate the analysis and reduce the calculation error.
