Which description best describes upfade in a multipath environment?
A.
In this situation, multiple signal paths are not sent at exactly the same time. The receiver
receives a positive crest on the primary signal and a negative crest on the secondary signal.
B.
In this situation, the multiple signal paths are distorted and difficult to understand.
C.
In this situation, the multiple signal paths are weaker than they should be because the signals
are out of phase with each other.
D.
In this situation, the signal is stronger than it should be because multiple signal paths are
received twice at exactly the same time, which results in the multiple signals being in-phase.
