I have been using such a source as an example for years.
I call it the SGCL, signal generator equipped with a
circulator and load resistor. Here's the diagram.

No reflections incident upon the source because they
are all dissipated in the resistor R. It's a great
way to simplify examples.


Cecil,

It is interesting that you ridicule zero impedance ideal sources, and
then you provide an example with a circulator. Do you really think a
circulator is more ideal than a good voltage source?
