Which of the following statements are true?
A. Frequency division multiplexing technique can be handled by digital circuits.
B. Time division multiplexing technique can be handled by analog circuits
C. Wavelength division multiplexing technique is used with optical fiber for combining two signals.
D. Frequency division multiplexing technique can be applied when the bandwidth of a link is greater than the bandwidth of the signals to be transmitted.
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: B. C and D only
Explanation
WDM combines optical signals on fibre (C), and FDM applies when link bandwidth exceeds the signals' bandwidth (D). FDM is analog and TDM digital, so A and B are swapped.
