If the input variable Y in Figure 1 is passed through the device in Figure 2 before going into the logic gate in Figure 1, compute the resulting value of the output at Z.
| X | Y |
|
0 0 1 1 |
0 1 0 1 |
0111
1011
1101
110
Explanation
B: (1011)
Y is originally 0101. After passing it through the NOT gate, in Figure 2, it becomes 1010.
| X | \(\overline{Y}\) | Z |
|
0 0 1 1 |
1 0 1 0 |
1 0 1 1 |
Z= 1011
