  3. A decoder takes n inputs and produces 2^n outputs. An encoder takes 2^n inputs and produces n outputs.
    A multiplexer selects one line from many lines.

  4. a decoder does not have a data input, whereas a demux has a data input.

  5. A demux simply selects an output line . It's a glorified switch. A decoder takes n inputs, and uses those inputs to determine which of the 2^n output lines is high.

  6. demux has only one output line but decoder has n inputs with 2^n output which is very high.

  7. A decoder converts binary coded information to unique outputs such as digits,symbols etc.
    Demux is a digital circuit that takes a single input and distributes it over several outputs.
