Demultiplexer vs. Decoder: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
A demultiplexer takes a single input signal and selects one of many data-output-lines; a decoder translates encoded data into an understandable format.
Key Differences
A demultiplexer is a device that receives a single input and directs it to one of several output lines. A decoder, conversely, interprets and converts encoded data into a recognizable format.
