Which of the following best explains why time‑division multiplexing can increase channel capacity?.
- A.It allows multiple signals to share the same channel by allocating them distinct time slots.
- B.It uses higher frequency bands to carry more data.
- C.It reduces the noise on each signal.
- D.It eliminates the need for error correction.
Model answer
What a good answer should say
- The correct option is 'It allows multiple signals to share the same channel by allocating them distinct time slots.'
Explanation
Why this works
Rule: By dividing the channel into time slots, several signals can use the same bandwidth sequentially. Substitution: Slot 1 → Signal A, Slot 2 → Signal B, etc.
Working: The channel is used more efficiently, effectively increasing capacity. Answer: The correct option is 'It allows multiple signals to share the same channel by allocating them distinct time slots.' Units/conclusion: This demonstrates how TDM increases channel capacity.
