I have a design , that has the right values for the cuttoff.
R1 = 39kΩ
R2 = 39kΩ
R3 = 9.1kΩ
C1 = 0.1uF
C2 = 0.1uF
C3 = 0.1uF
Center rejection frequency
f0 = 57.712584369[Hz]
f0 = 59.7382002206[Hz]
What about the harmonics that might exist ? What should I do to get rid of them or is there another thing I should add to filter harmonics? I will be making an ECG system, so i need to filter this cable noise, but I will be using shielded wiring.
Thanks
