Question

Q2. (i) Design a 2-input 1-output multiplexer, inside a hierarchical block. Explain your design. Name your block with your student number: eg “123456 multiplexer”.

(ii) Test your circuit in block form, showing the truth table from Multisim.

Answer 1

To create a heirarcha block for the 2 input 1 output mux we need to follow some steps. They are:-

1. Open your multisim

2. Goto Place>> New hierarchal block

   

3.Then new dialog box will be open and It ask where new hierarchial block should be save. Give the location

   and enter the no of inputs and outputs. Here our mux has 2 inputs and 1 selection line so total 3 inputs and 1     output

4.The new heirarchial box created with given inputs and output

5.   Click on the icon at the top left of the heirarchiay block

6. It will open a new window with given inputs and given outputs. So build your circuit using that inputs and outputs

7. give the input information to the heirarchial block and check for the output

8.In the above I have taken that Io=0 and I1=1; and My selection line value is 1 so it selects the I1 finally the ouput is displayed.
