Thanks for providing this URL. I used to use a very old program running under DOS for designing filters but the
AADE one looks like a very much better and improved tool. I also like the tutorial which makes the program useful for those who want to learn a bit about filters without the need for designing them..
Mike should certainly include this in his book.

(Upon opening the program a commercial for a LC-meter appears. Buit the program promises that after ten times it will not appear again.
By the way the LC-meter is a very fine tool; I have one myself and am very happy with it).

For filter design I use AADE Filter Design version 4.03

For circuit simulation I am looking at Linear Technology LTC Spice/SwitcherCAD III but don't claim to be competent yet.
