IIR/FIR滤波器和切比雪夫/巴特沃兹滤波器的关系
求问大佬们，IIR/FIR滤波器和切比雪夫/巴特沃兹滤波器到底什么关系啊，后悔大学专业课都用来睡觉了，唉????????
自己参考一下下面的文章：

Difference Between FIR Filter and IIR Filter (with Comparison chart) - Circuit Globe
The crucial difference between FIR and IIR filter is that the FIR filter is a type of filter that provides an impulse response of finite period. As against IIR is a type of filter that generates impulse response of infinite duration for a dynamic system.
