hi i've to design a bandpass active filter of 6th order PRB type, but i've a problem in the design procedure.
In order to obtain the desired filter i need to convert the bandpass transfer function in a lowpass transfer function.

\(H(s)=K0*\frac{B0 + B1*T(s) + B2*T^2(s) + B3*T^3(s)}{1 + F2*T^2(s) + F3*T^3(s)}\)

with: \(T(s)=\frac{k}{k+s}\)

what are the step formulas in order to obtain the lowpass transfer function H(s)?
Anyone could help me please?
