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 |
