Q
_____ is the multiplexing technique that shifts each signal to a different carrier frequency.
AA. Fdm
BB. Tdm
CC. Both fdm & tdm
DD. Pdm
Correct Answer:
A. A. Fdm
Explanation:
FDM is an abbreviation for Frequency Division Multiplexing. This technique is used when the bandwidth of the channel is greater than the combined bandwidth of all the signals which are to be transmitted. The channel is active at all times unless a collision occurs with another channel trying to use the same frequency. Some other multiplexing techniques are Time division multiplexing and Phase division multiplexing.
