Difference Between Multiplexing and Demultiplexing

Multiplexing vs Demultiplexing

  • 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 Demultiplexing
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
