| Question 9 |
(A) Frequency Division Multiplexing(FDM) 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?
| (A), (B), (C) and (D) are true. | |
| (A), (B), (C) and (D) are false. | |
| (A), (B) and (D) are false; (C) is true. | |
| (A), (B) and (D) are True; (C) is false. |
If Statement-B is FALSE then definitely Statement-C should be TRUE.
Option-A: We can ruled out based on the above two constraints.
Option-B: We can ruled out based on the above two constraints.
Option-C: Statement-B is FALSE because Wavelength Division Multiplexing (WDM) is an analog multiplexing Technique to combine optical signals.
If Statement-B is FALSE then definitely Statement-C should be TRUE.
Option-A: We can ruled out based on the above two constraints.
Option-B: We can ruled out based on the above two constraints.
Option-C: Statement-B is FALSE because Wavelength Division Multiplexing (WDM) is an analog multiplexing Technique to combine optical signals.
