Two common forms of multiplexing are: —Frequency Division Multiplexing (FDM). —Time Division Multiplexing (TDM). • Synchronous TDM. • Statistical TDM required frequency band. — Multiplexing equipment is needed to combine the modulated signals. • Synchronous TDM. — Can be used with digital signals or analog
In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal. This allows a single transmission medium such as a cable or optical
Frequency-division multiplexing (FDM): It is most popular and is used extensively in radio and TV transmission. Time-division Multiplexing (TDM): It is also called synchronous TDM, which is commonly used for multiplexing The idea is the same: we are combining different frequency signals. However, the difference is
FDM is an analog technique that can be applied when the bandwidth of a link is greater than the combined bandwidths of the signals to be transmitted. TDM. TDM is a digital multiplexing technique to combine data. Time-division Multiplexing (TDM). TDM can be implemented in two ways: synchronous TDM and

Multiplexing. It is the set of techniques that allows the simultaneous transmission of multiple signals across a single data link. Multiplexing is done using a device called. Multiplexer (MUX) that combine n input lines to generate one output line i.e. (many to one). At the receiving end a device called. Demultiplexer
