I put some course notes on line at
http://freeelectron.net/courses/

This one ("Electronics 2") ..
http://freeelectron.net/courses/ee420-electronics-2/
..  has some info about filters, starting around week 08.

There is some real theory (math) here.  It's not just find some
formulas and plug in.

Maybe eventually I will put more of my course notes on line.
