Question

Identify the gate represented by the block diagram as shown in fig.

A. `AND` gate
B. `NOT` gate
C. `NAND` gate
D. `NOR` gate

Answer 1

Correct Answer - D
The boolean expression of this gate is
`Y=overline((A+B).(A+B))= overline((A+B))+ overline((A+B)) = overline((A+B))`
which is for `NOR` gate.
