If the reflected current arrives out of phase with the forward current, then the final dissipation can actually be *reduced* by the mismatch. ***** Power is power. Phase is not a problem. Take the mafnitude of the transmitted power and teh magnitude of the reflected power. The results are phaseless. The magnitudes add linearly. QED james Cecil was talking about current, not power. You can't add power the way you can voltage and current. If you could, you could build a very nice perpetual motion machine just by using the reflections in a transmission line to add power so that the output was greater than the input. 73, Tom Donaly, KA6RUH |
