Default Transmitter Output Impedance

Hello Cecil,

Here's an easier example: Two EM waves superpose in a Z0=100 ohm
environment. Each wave is 100 volts at 1 amp = 100 watts. The phase
angle on wave1 is +60 degrees and the phase angle on wave2 is -60
degrees. The superposition results in a new wave of 100 volts at 1 amp
= 100 watts with a phase angle of zero degrees.

We superposed two 100 watt waves and the result was one 100 watt wave.
What happened to the other 100 watts?


If you want this question answered, please open a new thread as it is
not relevant to the original question.

Maybe people will ask you a circuit diagram showing the sources and
the combiner circuitry to enable calculation of the net power
delivered by each source. Otherwise people may consider your problem
as a single incident wave problem (as for these type of steady state
signals you first add complex amplitudes, then calculate powers).

I did respond to Walt's request because it is on topic and I stated
that such thing can happen (without given a numerical example).
