The output of the OR gate is 1:

1. only if both inputs are zero.

2. if either or both inputs are 1.

3. only if both inputs are 1.

4. if any of the inputs is zero.

To get output \(Y=1\) for the following circuit, the correct choice for the input is:
  

The following table is for which logic gate?

1. AND
2. OR
3. NAND
4. NOT

The logic behind the 'NOR' gate is that it gives:

Given Truth table is correct for:

1. NAND

2. AND

3. NOR

4. OR

A combination of logic gates is shown in the circuit. If \(A\) is at \(0\) V and \(B\) is at \(5\) V, then the potential of \(R\) is:

1. \(0\) V
2. \(5\) V
3. \(10\) V
4. Any of these

Logic gates X and Y have the truth tables shown below:

When the output of X is connected to the input of Y, the resulting combination is equivalent to a single:

1. NOT gate

2. OR gate

3. NAND gate

4. AND gate
