As we have seen, modulation is used to encode the information onto
a carrier wave, and may involve analog or digital methods.
It is only the characteristics
of the carrier wave which determine how the signal will propagate over any significant
distance.
The part that enters the new medium is
called the transmitted portion and the other the reflected portion. The part which
is reflected has a very simple rule governing its behavior. Make the following
construction:
