0. Given the following statements:
(A) Frequency Division Multiplexing is a technique that can be applied when the bandwidth of a link is greater than combined bandwidth of signals to be transmitted.
(B) Wavelength Division Multiplexing (WDM) is an analog multiplexing Technique to combine optical signals.
(C) WDM is a Digital Multiplexing Technique.
(D) TDM is a Digital Multiplexing Technique.
Which of the following is correct?

  • Option : D
  • Explanation :
  • Frequency Division Multiplexing is a technique that can be applied when the bandwidth of a link is greater than combined bandwidth of signals to be transmitted.Correct
  • Wavelength Division Multiplexing (WDM) is an analog multiplexing Technique to combine optical signals.Correct
  • WDM is a Digital Multiplexing Technique IncorrectIt is wavelength-division multiplexing
  • TDM is a Digital Multiplexing Technique.Correct
    • So, option (D) is correct.
