Q1: Answer the following as true or false
1- A MULTIPLEXER has multiple inputs and a single output.
2- The selection of one of the MULTIPLEXER inputs is done by select the desired
output.
3- A multiplexer has N data inputs and M select inputs, to determine the number of
select input it done by 2M.
4- A multiplexer has N data inputs and M select inputs, to determine the number of
select input it done by 2M = N.
5- MUX has 4 inputs (D0, D1, D2, D3) & 2 select lines (S0, S1) The output is:
Y = S1'SO'D0 + S1'SOD1 + sisO'D2 + S1'SO'D3.
6- In (DEMUX) It switches data from one input line to two or more data lines
depending on the select outputs.
7- De-multiplexer is used to connect a single source to multiple destinations.
8- A decoder is activating all the output that corresponds to the input number.
9- A decoder is activating only the output that corresponds to the input number, all
other outputs remain inactive.
1-A decoder has 4 inputs have 16 outputs.
2-Encoder has 16 inputs have 4 outputs.
