Figure 2.5-10 The generator end is reached
We can think of the voltage wave travelling back down the line towards the generator as the
superposition of the incident voltage wave, of amplitude E/2, and a reflected voltage wave of
identical amplitude and polarity. This ties in well with the idea that a voltage wave is fully reflected
by an open termination. The current travelling back down the line on the other hand may be seen as
the superposition of the incident current and a reflected current of the same amplitude and
opposite polarity which add up to zero! This ties in well with the intuitive idea that, as carriers reach
a dead-end they travel back in the opposite direction towards the generator.
