Have a look at some of the pages on filters in the 'Scots Guide'. This
inlcudes some basic stuff on designing simple filters with ICs.

Scots Guide? One of your pages?

Erm... Hundreds, actually. ;-)

Have a look at the 'Scots Guide' address in my sig, below. When there, go
to the section on 'Analog and Audio', and you will then find a link to some
pages on active filters. There are bits on related topics scattered around
the 'Guide'.

Slainte,
