I need help making a low bandpass, mid. bad pass, and high bandpass filter circuits i don't what resistors capacitors or inductors i should use i keep asking my teacher but when he explains it it just goes over my head could someone dumb it down for please?

i need to make one that does 0-500 Hz another that does 500Hz-5Khz and one that does 5Khz and over can someone please help?

Hi Montak,
What you need to do is to use the reactance of inductors and capacitors to either:
Shunt the freq's you don't want and / or pass the freq's that you do want.
Look at the formulas X(L) = (2 pi) X (f) x (L) and X© = 1/[(2 pi) x (f) x ©]

The higher the freq, the more the resistance of and inductor and the lower the resistance of a capacitor and vice versa.
A high pass filter will use a capacitor in series and an inductor in shunt, and a high pass is just the opposite. A band pass is a little more tricky, but you can use a pi network of caps and inductors to block or shunt the freq's you don't want and pass what you do.
I'm being vague on purpose.
Here's a decent reference site: http://www.tpub.com/neets/book2/4c.htm
Let me know how it's going.
Peace,
