Does anyone have a ressouce on how I can calculate second order section bandpass coefficients?
What I tried allready:
I used following formulas from the Book Electronic Circuits (U.Tietze, Ch. Schenk) for the Lowpass: My coefficients match exaclty (difference is max 2e-14) with the second order sequions of MATLAB for the same lowpass.
The results differ quite alot from MATLAB, expecially if the order is higher than 2. Also I dont think I can apply the formulas direcly for second order sections because the coefficients only depend on constant values.
