When are two wireless signals said to be in phase?
- when two identical signals are produced and one signal is slightly delayed from the other
- when two identical signals are produced exactly at the same time and their cycles vary slightly
- when two identical signals are produced exactly at the same time and their cycles match up
- when two different signals are produced and one signal is slightly delayed from the other
Explanation: Signals that are in phase, described as two identical signals that are produced exactly at the same time with matching cycles, tend to add together whereas signals out of phase cancel each other out.
