Question

Complete the tutorial provided with Logisim 2.7.1. The tutorial is under the “Help”
menu in Logisim or at http://www.cburch.com/logisim/docs/2.7/en/html/guide/tutorial/.
Insert a picture of the circuit, as drawn in Logisim, into your homework submission. Include a
text label with your name and the current date in the Logism diagram. Use the “Export
Image” function in the “File” menu to save an image file and then insert that in your
submission. Uncheck the “Printer View” box when exporting the image from Logisim. Do not
provide the picture as a separate file.

Answer 1

The XOR operation circuit is drawn in Logisim software: AB= 4B+Ā.B Truth table of XOR-gate: AB AB 000 011 101 1 1 0 For this operation, the xor circuit requires two AND gates, one OR gate and two NOT gate. Open Logisim application : Add two AND gates, one OR gate and two NOT gates as shown below and then connect wiring as shown below.

Set text to the input and output gates. NOTIX) NOT(X). xor=NOT(X).y+x.NOT(Y) o X.NOT(Y) NOT(y)

Final image with name and date : xor-operation Name: your name Date: 18/09/2019 NOT(X) * Doe NOT(X).y xor=NOT(X).y +x.NOT(y) X.NOT(y) NOT(y)

Testing the xor-circuit by adding 2 Add-pins to x and y and 1 Add-pin for output. For x=0,y=0, the result is 0 xor-operations Name: yourname Date : 18/09/2019 x 0 y 0 Do

For x=0,y=1, the result is 1 xor-operation Name: yourname Date: 18/09/2019 XO y 0 Do

For x=1, y=0, the result is 1 ...... ........ ...... xor-operation .... : xor-operation Name: your name: Date: 18/09/2019 y 0 I Do

For x=1,y=1, the result is 0 xor-operation Name: yourname Date: 18/09/2019 XOD

Note : Download Logisim 2.7.1 and draw the circuit and test the results as shown above figures.
