The impedance of the perfect voltage source is supposed
to be zero. I, like you, suspect that is a complete
impossibility. What I would like to see is a TV signal
fed through a source only to emerge unscathed on the
other side and viewable on a TV screen without distortion
just as the theory predicts.
