Answer / uma sharma

Multiplexer-
1. Many inputs & one output.
2. Data select lines.
3. Parallel to serial conversion.
4. When we design multiplexer, we don't need additional gates.
5. Example- 8:1, 16:1, 32:1

Demultiplexer-
1. One inputs & many output.
2. Data distributer.
3. Serial to parallel conversion.
4. When we design demultiplexer, we need additional gates.
5. Example- 1:8, 1:16, 1:32

Answer / saranii

for multiplexing many input single output for
demultiplexing single input many output

Answer / nida yasmeen

MUX IS USED AT TRANSMITTER SIDE, DEMUX IS USED AT RECEIVER
SIDE,
MUX WILL CONVERT MANY INTO 1 BUT PASSES ONLY ONE
INFORMATION AT A TIME,DEMUS WILL RECEIVE ONE SIGNAL BUT
PASSES TO DIFFERNT DESTINATIONS,

Answer / akash

MUX: It is a combinational circuit that selects binary
information from one of many input lines directs it a
single output.
DEmux:It takes a singledata input and n address input and
2^n outputs.
n address input determine whih data output is going to have
same value as data output.

Answer / priyadarshi sahu

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.

Answer / vidhyajith

a multiplexer or mux consists of a many inputs and one
output.
a demultiplexer or demux consists of a one input to many
outputs.

Answer / ashok

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

Answer / poonam

in multiplexer if we give many input signals it will convert
in one output
but in demultiplexer it convert one input signal to many
output signals

Answer / rashu

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

Answer / darshi

Multiplexer --- Many inputs & Single out put.

Example - 4-1 / 8-1 multiplexer

Demultiplexer - Single input & Many outputs

Example - 1-4/ 1-8 demultiplexers
