For starters, here are a few sites to look at for ideas. Your choice from
extremely simple (OK but not great performance) to fairly elaborate (really
fine performance).
http://www.redcircuits.com//Page10.htm
http://www.national.com/an/AN/AN-346.pdf
http://www.electronics.50g.com/cpowers.htm
http://www.opamplabs.com/disp.htm
http://sound.westhost.com/project25.htm

Take a look and see if there's one or two that interest you, then maybe come
back with specific questions.
