You need to supply a lot more information. What is the application? What sort of signals are you processing, and what end result do you need. Are you sure you have the correct frequencies in your table? You can't design a filter with such precise frequencies, component tolerances and drift won't allow it.You don't use band pass filters if the frequencies are correct, but rather cascaded low pass and high pass sections.You have to specify two frequencies at the band edge, the (normally)3db point, and an attenuation at a specified stop band frequency. This gives two frequencies and two attenuation figures. This determines the order of the filter, that is how many poles and zeros are required to meet your specifications for the type of filter you choose. The filter type (bessel, butterworth , elliptic etc) determines things like phase shift , group delay, transient response, the complexity of tuning, etc.I suggest that you find a filter design program online, or download for windows aade or elsie . The Tools section of RFsim has a simple filter synthesis program, Qucs has a more comprehensive one. These will give you some idea of what parameters are needed.You won't be able to do a passive filter at low frequencies (audio) without using large inductors , it is common to resort to active filters in that case. In the GHz range, distributed rather than lumped components are necessary.Filter design is a very complex subject, many compromises are normally necessary. I suggest you look at some texts to get a better understanding of the topic, look on the web, ADI text may help. When you have sorted some of these issues, come back to the forum,
