"If a cable is terminated in a resistance exactly equal to its characteristic impedance, all of the energy is absorbed in the resistance and none is reflected. Such a cable will not resonate."

The corrolary to that in my case is, if an explanation terminates at cerebral folds with a resistance exactly equal to the explanation's characteristic impedance, all of the knowledge is absorbed in the cerebral folds and none is reflected.

I'd say I absorbed about half of the explanation but I think that was sufficient to keep me from making the evening news.

Are there any good one-stop resources online, or printed books, that can be recommended for me to read and obtain a better grasp of the science involved?

Thanks!

Yes. You will need to connect an R-C network to the secondary. - Al Sekela 22:05:03 04/27/07 (6)

I'm a bit confused - "characteristic impedance"? - Christopher Witmer 01:33:13 04/28/07 (0)
