Explanation:
Detailed explanation-1: -8. In TDM, the transmission rate of a multiplexed path is always the sum of the transmission rates of the signal sources. 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.
Detailed explanation-2: -Time Division Multiplexing (TDM)
Detailed explanation-3: -Multiple multiplexing is a technique used to allot more than one slot in a frame to a single input line. Multiple-slot multiplexing. Pulse stuffing. Sometimes the bit rates of sources are not multiple integers of each other. Then to make the data rate compatible, dummy bits are added to input lines .
