We postulated the following driving-source interface:
Non-physical because:
- Velocity transmission is zero
no power delivered
- There can be no traveling force (voltage) wave
in a zero impedance (which would ``short it out'')
- Recall power waves:
if
- Zero source-impedances can be a useful idealization, but be careful
- Exercise: Study the case of small
