電子式分頻器(濾波)線上計算器

Active filter crossover schematic

輸入想要的分頻頻率: Fol = Foh = Hz,
計算出的值直接配合上圖配置
R = KΩ C = µF
R2 = KΩ C2 = µF
R4 = KΩ C4 = µF
R7 = KΩ C7 = µF

計算的方式:
R的理論值 ...
(頻率Fc < 200 Hz時選擇使用R = 100 KΩ，否則 R = 10 KΩ):
C = (10/R)*50
2 π F		      C2 = 2455.3
2 π F R		      C4 = 2108.9
2 π F R		      C7 = 193.1
2 π F R
 
R2 = 407.4
2 π F C		   R4 = 474.2
2 π F C		   R7 = 5176.6
2 π F C		   (C in

(R in		 µF)

KΩ)
