Select Add Logic output >> draw it in working space. |
Next we will add one logic output to the AND gate.
Now, click on the Draw menu, click on Logic gates, Input and Output. Then Select Add Logic output and draw it in the working space. Right click on the logic output and select the Edit option. In the pop-up window, check the Numeric box and click on the OK button to save the changes. By doing this, the output value will be shown in either 0’s or 1’s.
