Given two inputs, 1 and 1, which logic gate(s) will produce an output of 1?
Question



Given two inputs, 1 and 1, which logic gate(s) will produce an output of 1?

A.

AND

B.

NAND

C.

NOR

D.

OR and XNOR

E.

both a and d

Correct option is E

The correct answer is option (e). Both OR and XNOR gates produce an output of 1 when the inputs are 1 and 1. The OR gate outputs 1 whenever at least one input is 1, while the XNOR gate outputs 1 when both inputs are the same. AND Gate: Outputs1only when both inputs are1. It produces1in this scenario.​
Important Key Points:
1. The OR gate outputs 1 when any of its inputs are 1, including the case where both are 1.
2. The XNOR gate outputs 1 when both inputs are the same, which includes both 1 and 1.
Knowledge Booster:
· NAND Gate: Outputs 0 when both inputs are 1, which is the inverse of the AND gate's output.
· NOR Gate: Outputs 1 only when both inputs are 0; otherwise, the output is 0.
· XOR Gate: Outputs 1 when the inputs are different. When both inputs are 1, the output is 0.
