need help with a block diagram for a graphics equalizer

[kontradiktor]

i need to come up with a block diagram for a graphics equalizer and i can't really think what they should be

it needs to have a minimum of 5 blocks so any help would be much appreciated
and if you would be so lovely and kind to tell me what circuit i could use in each would be great

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.
