Figure 24. A 3 Amplifier Bi-Quad Notch Filter

Ex: fNOTCH = 3 kHz, Q = 5, R1 = 270k, R2 = R3 = 20k, R4 = 27k, R5 = 20k, R6 = R8 = 10k, R7 = 100k, C1 = C2 =

0.001

μF

Better noise performance than the state-space approach.

Figure 25. A 4th Order 1 kHz Elliptic Filter (4 Poles, 4 Zeros)

R1C1 = R2C2 = t

′1C′1 = R′2C′2 = t′

fC = 1 kHz, fS = 2 kHz, fp = 0.543, fZ = 2.14, Q = 0.841, f′ P = 0.987, f′ Z = 4.92, Q′ = 4.403, normalized to ripple BW
