Exam-style question
Try this first
In a time‑division multiplexed system, how are the individual signals recovered at the receiver?.
- A.By filtering each signal's frequency band.
- B.By demultiplexing the time slots and assigning them to the correct signal.
- C.By demodulating the amplitude variations.
- D.By using a separate cable for each signal.
Model answer
What a good answer should say
- The correct option is 'By demultiplexing the time slots and assigning them to the correct signal.'
Explanation
Why this works
Rule: The receiver uses the same clock to identify time slots. Substitution: Slot 1 → Signal A, Slot 2 → Signal B, etc.
Working: Each slot is routed to the appropriate output, reconstructing the original signals. Answer: The correct option is 'By demultiplexing the time slots and assigning them to the correct signal.' Units/conclusion: This shows how signals are recovered in TDM.
