1. Multiplexer :
Multiplexer is a data selector which takes several inputs and gives a single output.In multiplexer we have 2n input lines and 1 output lines where n is the number of selection lines.
2. Demultiplexer :
Demultiplexer is a data distributor which takes a single input and gives several outputs.In demultiplexer we have 1 input and 2n output lines where n is the selection line.
Difference between of Multiplexer and Demultiplexer :
|Multiplexer processes the digital information from various sources into a single source.||Demultiplexer receives digital information from a single source and converts it into several sources|
|It is known as Data Selector||It is known as Data Distributor|
|Multiplexer is a digital switch||Demultiplexer is a digital circuit|
|It follows combinational logic type||It also follows combinational logic type|
|It has n data input||It has single data input|
|It has a single data output||It has n data outputs|
|It works on many to one operational principle||It works on one to many operational principle|
|In time division Multiplexing, multiplexer is used at the transmitter end||In time division Multiplexing, demultiplexer is used at the receiver end|
