- Multiplexing and Demultiplexing are two fundamental operations in data communication.
- The Key Difference Between Multiplexing and Demultiplexing is that Multiplexing takes several inputs and gives a single output whereas Demultiplexing takes a single input and gives several outputs.
- Multiplexing and Demultiplexing both have different features and functionalities, here is a comparison of some key features between them.
|Multiplexing is a method or technique in which more than one signal are combined into one signal||De-multiplexing is the reverse of multiplexing. In this method, a multiplexed signal is again decomposed into individual signals.|
|Known as Data Selector||Known as Data Distributor|
|Multiplexing has 2n input data lines||Demultiplexing has a single input line|
|Parallel to serial conversion is there||Serial to parallel conversion is there.|
|When we design multiplexer, we don’t need additional gates.||Additional gates are included when designing De-multiplexer|
|Works on many to one operational principle||Works on one to many operational principle|
