Welcome to our site! EDAboard.com is an international Electronics Discussion Forum focused on EDA software, circuits, schematics, books, theory, papers, asic, pld, 8051, DSP, Network, RF, Analog Design, PCB, Service Manuals... and a whole lot more! To participate you need to register. Registration is free. Click here to register now.
First let start with the fundamental, i.e., the actual bandpass filter requirement such transition band (f1, f2) cutoff frequencies, passband ripples, phase linearity, etc... From there you will be able to come to a set of poles/zeros and the filter characteristic (such as Elliptic, Bessel, Butterworth, Chebyshev, ...) to meet the requirement.
You stated that it's a 4th order filter => 4 poles but how did you come to this conclusion? Remember that any Spice tool is as the name said it's just a "tool", i.e., for simulation only. You must implement the actual circuit then use the tool to validate you design.
