A single channel is shared by multiple signals by _____________________?
Correct answer: C. multiplexing
- A. analog modulation
- B. digital modulation
- C. multiplexing
- D. none of these
Explanation
Multiplexing combines multiple signals so they can share one communication channel, with the signals separated again at the receiving end. Modulation changes a carrier signal but does not by itself mean that several signals share one channel.
