Which multiplexing technique used to transmit digital signals?
A
FDM
B
TDM
C
WDM
D
FDM & WDM
Explanation: 

Detailed explanation-1: -Time division multiplexing (TDM)-synchronous TDM: Multiple digital signals or analog signals carrying digital data can be carried on a single transmission path by interleaving portions of each signal in time. The interleaving interval can be one bit, one octet, or one block of a fixed size of octets.

Detailed explanation-2: -Time-division multiplexing (TDM) is a method of putting multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Each individual data stream is reassembled at the receiving end based on the timing.

Detailed explanation-3: -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-4: -In analog multiplexing, the most used technique is Frequency Division Multiplexing (FDM). This technique uses various frequencies to combine streams of data, for sending them on a communication medium, as a single signal.
