Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

In TDM, the transmission rate of a multiplexed path is always ____ the sum of the transmission rates of the signal sources.

A	Greater than
B	Lesser than
C	Equal to
D	Equal to or greater than

Explanation:

Detailed explanation-1: -Explanation: In TDM the transmission rate provided by the path that is multiplexed will always be greater than the sum of transmission rates of the single sources. This happens because the transmission rate is provided to each source only for a small period of time.

Detailed explanation-2: -Time-division multiplexing (TDM) is a digital multiplexing technique for combining several low-data-rate signals into one high-data-rate signal. In TDM, the available transmission channel is time-shared by a number of different sources.

Detailed explanation-3: -TDM and FDM are both multiplexing techniques. FDM is meant for analog signals, while TDM works well with both analog as well as digital signals. However, TDM is mostly used in digital communications only. In TDM, syncronization pulse is important; whereas in FDM, Guard Band is required.
