Interesting article on DC Restoration
 

Came across this while looking at other things... I never really understood how DC restoration works, but have an electrical engineering background... this link may help if you're in the same boat, scroll to page 85.

Thank you for posting that. I am going to read it, too.

The website I found the article on is absolutely awesome - it's like having the university technical periodical archives right on my desktop. When I was a student and had enough of studying I would take a break by grabbing a year of whatever periodical and reading the interesting articles. I like how this opportunity is now open to everyone, not just people with access to a good library.

But its utterly unreadable. The good news is that our library has it physically ..
I've read it many times. It helps to have the second-largest
university library in the world (after Harvard) (Admittedly
depending on how you count.)
