It isn't highly accurate as Spice might be, but it's certainly close enough for a basic PS design. It allows you to compare RC vs. LC filters at constant R loads, constant I loads, or stepped I loads. Pretty versatile for the hobbyist. -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Never take a laxative and a sleeping pill at the same time!! |
