这个算法是用于绘制低通滤波器的幅度响应图,它使用了Butterworth设计和双线性变换。Butterworth设计是一种常见的滤波器设计方法,它可以实现平坦的通带响应和陡峭的截止频率。双线性变换则是一种数学方法,可以将连续时间系统转换为离散时间系统。 具体而言,该算法首先会通过输入的滤波器参数计算出Butterworth滤波器的系数。

The Butterworth filter is recursive, i.e., past values of the output are used as input, so a phase shift is introduced unless the data are filtered forward and backward through the same filter. When this is done, the filtered signal differs only slightly from that of other low-pass ...
Although there are many filter types and ways to implement them, here’s an active low-pass filter that’s greatly simplified if R1=R2 and the op amp stage is a unity gain follower (RB=short and RA=open). Designing a 2-pole Butterworth filter requires just a few steps. ...
