Question

Draw symbol of NOR gate and draw truth table for its output.

Hint:

In a NOR gate, the output is true (1) only when all inputs are false (0).

Answer 1

Step 1: Symbol of NOR Gate

The symbol of a NOR gate is a combination of an OR gate with a NOT gate. It has two or more inputs and one output. The output is true (1) only when all inputs are false (0).

Truth Table of NOR Gate

Input A	Input B	Output (A NOR B)
0	0	1
0	1	0
1	0	0
1	1	0

The Boolean expression for the NOR gate is represented as: \[ Y = \overline{A + B} \] where \( A \) and \( B \) are the inputs, and \( Y \) is the output.
