Choose the logic operation carried out by the following current :

Concept:

NOR Gate:

• It is a digital circuit having two or more inputs but only one output.
• It gives a high output if both the inputs are low (0) otherwise it gives a Low output (0).
• It is described by the Boolean expression: \(\overline {A + B} = Q\)
• The above logic gate is the NOR gate.

The truth table for NOR gate:

Explanation:

We know that \(\over\overline {A } + \overline {B}\) = AB

This can be compared with two inputs AND Gate.

The correct answer is option (2)
