1. Verification of all Gate.

2. So the gate gives true value on 0 and 1 , lighting the digital LED.

3. The AND gate gives a high output (1) only if all its inputs are high.

    The outputs of all NOR gates are low if any of the inputs are high.

    The 'X-OR' gate will give a high output if either, but not both of its two inputs are high.

    The 'XNOR' gate circuit does the opposite to the XOR gate. It will give a low output if either, but not both of its two inputs are high.
