WebThe Butterworth Low-Pass Filter 10/19/05 John Stensby Page 2 of 10 the derivative of the magnitude response is always negative for positive Ω, the magnitude response is monotonically decreasing with Ω. For Ω >> Ωc, the magnitude response can be approximated by 2 a 2n c 1 H(j ) (/ ) Ω≈ ΩΩ. (1-2) Butterworth Filter Design Procedure Webs 2 + 0.7654s + 1. You can design a 4th-order Butterworth lowpass filter with this information. Simply substitute values from the above quadratic expressions into the denominator of equation 4. Thus, C2C4 = 1 and 2C4 = 1.8478 in the first filter, implying that C4 = 0.9239F and C2 = 1.08F.
