Compare and contrast analog and digital RF signals.

What will be an ideal response?

RF data is transmitted as analog or digital signals. An analog RF signal is a continuous wave that oscillates between positive and negative voltage, as with an audio or video broadcast.  An analog signal has an infinite number of points within the carrier's range. Digital RF signals also oscillate between positive and negative voltage, but they are divided into discrete segments or defined states within the carrier's range. When a binary signaling method is used, the range has only two significant states, which are represented by 1s or 0s.
