The transfer function of the second-order lowpass filter is given by
a1 = 13085.9097, a0 = 8.5620516×107
? 0 = a 0= 9253.1355 rad/s
The Q value is given by
Q = ? a1
0= 0.7071
The normalized component values are given by
C1 = 1 F, C2 = 1 F, R2 = 1 ?, RB = 1 ? , RA = 2 – 1/Q = 0.5858 ?
Ra = 3 – 1/Q = 1.5858 ?, Rb = (3Q-1)/(2Q-1) = 2.7071 ?
Application of the magnitude scaling (km = 1000) and frequency scaling (kf = ?0 = 9253.1355) yields
C1 = 1F
k m k× f
= 0.10807 ?F
C2 = 1F
k m k× = 0.10807 ?F

R2 = 1×1000 ? = 1 k?
RB = 1×1000 ? = 1 k?
RA = 0.5858×1000 ? = 585.8 ?
Ra = 1.5858×1000 ? = 1.5858 k?
Rb = 2.7071×1000 ? = 2.7071 k?
