Time-Division Multiplexing (TDM) is a type of digital or (rarely) analog multiplexing in which two or more signals or bit streams are transferred apparently simultaneously as sub-channels in one communication channel, but are physically taking turns on the channel. Which is the best description of time-division multiplexing?
A.
One TDM frame consists of multiple timeslot per sub-channel.
B.
the time domain is only one recurrent timeslots of fixed length
C.
Individual source signals are combined into a composite signal, which allows a capacity equal to or greater than the sum of the component signals.
D.
All sources get an interleaved slice of time, which offers the entire frequency range allocated for that timeslot
D
