WebDec 28, 2024 · Following the example from this book, page 450, using the Butterworth co-efficients for Second-Order Filter Parameters α = 1.414 and b = 1.0. Calculating: R4 = 2 - α = .586 ohms. Calculating: R3 = 1 + .586/1 = 1.586 ohms. This resistor ratio is providing a gain of 1.586 as per the Butterworth coefficients. Thus my circuit looks like this: WebOct 6, 2024 · Here we choose Butterworth Low-pass filter. To design a Butterworth we just need the number of the order N and the Cutoff frequency Wc. Or we can use the passband cutoff and stopband cutoff to calculate the N and Wc. Notice that when the Butterworth order is 2, the filter is also called Biquad filter.
