Butterworth-(巴特沃斯)滤波器设计参考.pdf,Butterworth (巴特沃斯)滤波器设计参考 -- By Water 在嵌入式音频产品开发过程中经常会到LPF (LowPassFilter 低通滤波器)和HPF (HighPassFilter 高通滤 波器),一般情况下都是离线用工具(如:Matlab)设计好滤波器的参数 (F
按滤波器⼯作频 率范围的不同,可分为 : 低低通通滤波器 (Low-pass Filter,LPF) ⾼⾼通通滤波器 (High-pass Filter,HPF) 带带通通滤波器 (Band-pass Filter,BPF) 带带阻阻滤波器 (Band-rej ection Filter,BRF) 全全通通滤波器 (All-pass Filter,APF) 仅由电阻、电容、电感这些⽆源器件组成的...

configuration. The Sallen-Key design (shown in Figure A-1) is a biquadratic or biquad type filter, meaning there are two poles defined by the circuit transfer function (1) where H 0 is the DC gain of the biquad circuit and is a function only of the ratio of the two resistors ...
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 ...

butterworth）巴特沃兹滤波器(Butterworth)特点：具有通带内最大平坦的振幅特性，且随f↗单调↘ 其幅度平方函数具有如下形式：式中，N为整数，称为滤波器的阶数，N越大，通带和阻带的近似性越好，过渡带也越陡。如下图所示：图巴特沃兹filter 振幅平方函数 过渡带：通带→阻带间过渡的频率范围，Ωc：截止频率。
