The gate is either _________
A. A NAND or an EX-OR
B. An OR or an EX-NOR
C. An AND or an EX-OR
D. A NOR or an EX-NOR
Answer:D
The gate is either _________
A. A NAND or an EX-OR B. An OR or an EX-NOR C. An AND or an EX-OR D. A NOR or an EX-NOR
Explanation: The output of a logic gate is 1 when all inputs are at logic 0. The gate is NOR. The output of a logic gate is 1 when all inputs are at logic 0 or all inputs are at logic 1, then it is EX-NOR. (The truth tables for NOR and EX-NOR Gates are shown in above table).
