MUX IS USED AT TRANSMITTER SIDE, DEMUX IS USED AT RECEIVER
MUX WILL CONVERT MANY INTO 1 BUT PASSES ONLY ONE
INFORMATION AT A TIME,DEMUS WILL RECEIVE ONE SIGNAL BUT
PASSES TO DIFFERNT DESTINATIONS,
incase of multiplexer if we giveseveral inputs,then at the
output we get only one output,but incase of demultiplexer
if we give one input,then at the output we get several
outputs.means multiplexer is the opposit of demultiplexer.
I agree with Priyadarshi sahu.But here one thing do u
remember.actually in telecommunications,ISP we use both the
mux and demux .
Mux means --we give many inputs and get single input only
Demux-------we give single input and get more outputs.
ex:consider one Internet service provider(ISP) location
Here in POP(Point of Presence)all are using MUX and Demux
because lot of customers are connected and at customer side
also they connected lot of systems and the data flow b/w all
the systems as well as pop
MUX: It is a combinational circuit that selects binary
information from one of many input lines directs it a
DEmux:It takes a singledata input and n address input and
n address input determine whih data output is going to have
same value as data output.
a mutiplexers selects one line from many lines i.e one output from no. of inputs.whereas demutiplexers is a inverse of mutiplexers. It distribute no. of output from one input i.e many lines from one lines
