BUTTORD Butterworth filter order selection.
[N, Wn] = BUTTORD(Wp, Ws, Rp, Rs) returns the order N of the lowest
order digital Butterworth filter that loses no more than Rp dB in
the passband and has at least Rs dB of attenuation in the stopband.
Wp and Ws are the passband and stopband edge frequencies, normalized
from 0 to 1 (where 1 corresponds to pi radians/sample). For example,
Lowpass: Wp = .1, Ws = .2
Highpass: Wp = .2, Ws = .1
Bandpass: Wp = [.2 .7], Ws = [.1 .8]
Bandstop: Wp = [.1 .8], Ws = [.2 .7]
BUTTORD also returns Wn, the Butterworth natural frequency (or,
the "3 dB frequency") to use with BUTTER to achieve the specifications.

[N, Wn] = BUTTORD(Wp, Ws, Rp, Rs, 's') does the computation for an
analog filter, in which case Wp and Ws are in radians/second.

When Rp is chosen as 3 dB, the Wn in BUTTER is equal to Wp in BUTTORD.

【BUTTORD:巴特沃兹滤波器阶数选择函数】
[N,Wn] = BUTTORD(Wp,Ws,Rp,Rs) returns the order N of the lowest order digital Butterworth filter that loses no more than Rp dB in the passband and has at least Rs dB of attenuation in the stopband.
【运行[N,Wn] = BUTTORD(Wp,Ws,Rp,Rs)语句将返回一个通带损耗不大于Rp分贝且阻带衰减不小于Rs分贝的最低阶巴特沃兹数字滤波器的阶数N】
Wp and Ws are the passband and stopband edge frequencies,normalized from 0 to 1 (where 1 corresponds to pi radians/sample).【其中Wp和Ws分别是通带和阻带归一化的边缘频率,通过归一化化为0到1之间的数值,1代表pi弧度每采样.】
For example,
Lowpass:Wp = .1,Ws = .2
Highpass:Wp = .2,Ws = .1
Bandpass:Wp = [.2 .7],Ws = [.1 .8]
Bandstop:Wp = [.1 .8],Ws = [.2 .7]
比如：
低通:Wp = .1,Ws = .2
高通:Wp = .2,Ws = .1
带通:Wp = [.2 .7],Ws = [.1 .8]
带阻:Wp = [.1 .8],Ws = [.2 .7]
BUTTORD also returns Wn,the Butterworth natural frequency (or,the "3 dB frequency") to use with BUTTER to achieve the specifications.
【BUTTORD函数也可以返回Wn值——这个巴特沃兹（滤波器）的自然频率（也称为3分贝的频率【学控制,通信的应该都懂这个概念.】）——来配合BUTTER函数获取参数.】
[N,Wn] = BUTTORD(Wp,Ws,Rp,Rs,'s') does the computation for an analog filter,in which case Wp and Ws are in radians/second.
【语句[N,Wn] = BUTTORD(Wp,Ws,Rp,Rs,'s')针对Wp和Ws单位为“弧度/秒”的模拟滤波器进行计算】
When Rp is chosen as 3 dB,the Wn in BUTTER is equal to Wp in BUTTORD.
【当Rp选为3分贝时,BUTTER函数计算出的Wn和Wp相等】
