GATE | GATE-CS-2017 (Set 1) | Question 28
Consider the Karnaugh map given below, where X represents “ don’t care” and blank represents 0.
Assume for all inputs (a, c, d) the respective complements (a’, b’, c’, d’)are also available. The above logic is implemented 2-input NOR gates only.
The minimum number of gates required is ____________.
Note: This questions appeared as Numerical Answer Type.
Solving the above k- map,
= ca = ac = (a’ + c’)’
Since complement of variables are also available. So, this can be implemented using one NOR gate.
Therefore, option A is correct
