Logic gates

Question

The logic behind 'NOR' gate is that it gives

Moderate

A

High output when both the inputs are low
B

Low output when both the inputs are low
C

High output when both the inputs are high
D

None of these

Solution

The Boolean expression for 'NOR' gate is Y = $A + B$
i.e., if A = B = 0 (Low), Y = $0 + 0 = 0 = 1$ (High)
