Bandwidth filter
« on: March 23, 2008, 09:24:06 AM »
I would like a bandwidth filter that will only permint a narrow width at 4000 Hz as narrow as can be and if possible this should be done w/o op-amps.

Can someone help me?

Why not op amps? You get nice active filters

Although i believe you should use op-amps, try this for a chance

Well, i tried op-amps for a chance. They are very very good. this 741 gizmo is excellent. I was afraid to use them as i know nothing but i have just begun to love them!
