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 and Chebyshev filters are high order filter designs which have significantly different characteristics, but both can be realized by using simple first order or biquad stages cascaded together to achieve the desired order, passband response, and cut-off frequency. The Butterworth filter ...
