Tool/software: WEBENCH® Design Tools
Hello, I am using the your Filter design tool to design the 2nd order, 6th order Bandpass filter CHEBYSHEV and The design is not tallying with the formulas of cut off frequency. My understanding is that the Fc value for 2nd order is 1/2*pi*sqrt(R1*R2*C1*C2). Please let me know if you agree with this formula or not, also I would like to know the Fc formula for sixth order Bandpass filter as well. Thanks in advance for your help, I look forward to your reply.
