Third topic post actually. All three on the same subject.

What it should show is a low pass filter in parallel with 3 band pass filters and either a fourth band pass filter or a high pass filter. Each filter output goes into an attenuator and all of the attenuators outputs are in parallel. Each filter can be active or passive and could either be pure attenuation or could include amplification. You have a lot of decisions to make depending upon the application.
