Gene, I cannot find anywhere in the s-parameter information
where some of the network must be hidden inside a black box.
I always thought an s-parameter analysis could be done without
a black box. Could you help us out here and point out exactly
where it says a black box is a requirement. Seems to me the
purpose of an s-parameter analysis is to alleviate ignorance
which obviously doesn't match your agenda.
