I've enjoyed reading this and related threads. Some comments have been
made about using calculus. Though I spent a significant portion of my
pre-retirement life attempting to teach that subject to undergraduates, I
don't believe in using calculus whenever simple geometry and/or algebra
makes it unnecessary. A proof that avoids calculus can be meaningful for
those who don't know calculus, or who haven't used it for a while.

The the area within the rho=1 circle of the Smith is reserved for
passive networks. Outside rho=1, where the reflection is greater than
one, is reserved for active networks only.
