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.

This includes any software that is still available, whether it is

Also, do you have favourite web sites or discussion groups to

Are there any other ways you use a computer to improve your ability
