Hi, Walter, I opened your doc and found a lot of "Error! Reference source not found."inside. It seems to be some references are lost. Is this only me or anyone else?

I also put in a new section "Best Practices" (page 4), which contains my suggested language for Scaling, Global Parameter, Naming Conventions, Exponent Range, and Scale Factors. All of these are obviously up for debate. Walter Walter Katz Chief Scientist Signal Integrity Software, Inc. wkatz@xxxxxxxxxx 303.449-2308
