A couple months ago a request for a high pass digital filter algorithm
written in QuickBasic came over the network. I recently came across some
info on a technique to do this. Unfortunately, I erased Terry's address
when I was doing some electronic house cleaning.
Terry, please email me if interested. Sorry to all the other folks for
adding to the clutter in your mailboxes!
