Question

In time-division-multiplexing, each multiplexed signal occupies;

  1. A. A Fraction of the Transmission Bandwidth
  2. B. The Entire Transmission Bandwidth (Correct answer)
  3. C. A Bandwidth Equal to the Bandwidth of each input signal
  4. D. None of the above

Correct Answer

Option B — The Entire Transmission Bandwidth

Detailed Solution & Explanation

The correct answer is The Entire Transmission Bandwidth.

Key Points

  • In Time Division Multiplexing (TDM), each signal is given the entire transmission bandwidth, but only for its own allotted time slot.
  • The channels are separated in time, not in frequency — they take turns using the full channel.
  • This is the direct opposite of Frequency Division Multiplexing (FDM), where every signal occupies a fraction of the bandwidth continuously, for all of the time.

Additional Information

  • The trade-off is easy to remember: TDM shares time, FDM shares frequency.
  • TDM suits digital and pulse-modulated signals, and it avoids the intermodulation distortion and crosstalk that can affect FDM systems.
