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 = C = F
R2 = C2 = F
R4 = C4 = F
R7 = C7 = F

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
