Use the devices in Figures 1 and 2 to answer the questions given that the input variables X and Y have values of 0011 and 0101 respectively as shown in Table 1.
| X | Y |
|
0 0 1 1 |
0 1 0 1 |
Compute the value of the output Z in Figure 1 using the values of X and Y given.
0001
0110
0111
1000
Explanation
C: (0111)
The gate here is an OR gate that only gives 0 when both inputs are 0, else it gives 1.
| X | Y | Z |
|
0 0 1 1 |
0 1 0 1 |
0 1 1 1 |
Z = 0111
