Question

Difference between multiplexer and demultiplexer in tabular form books.google.co.in

Answer 1

Multiplexer is a electronic device which only selects a single  input out of the many inputs signal and then this selected signal is sent in the form of single line. A multiplexer is also known as " data selector" or "mux" which can be use in order to enforce the "Boolean function",

While one the other hand a "de-multiplexer" just used the one input signal in order to generate many , so we can say that it has only one inputs and it's outputs are many. it is also sometimes known as "demux". 

Answer 2

Multiplexer and demultiplexer are two integrated circuits that perform the inverse functions of each other.

Multiplexer

# This is a chip that features multiple inputs and one output.

# It follows parallel to serial conversation.

# No additional gates are needed to design a multiplexer.

# Format: 8:1, 16:1, 32:1

Demultiplexer

# This is a chip that features a single input and multiple outputs.

# It follows serial to parallel conversation.

# Additional gates are needed to design a multiplexer.

# Format: 1:8, 1:16, 1:32
