The below truth table corresponds to A B Y 0 0 1 1 0 1 0 1 1 1 1 0

Options

  1. ANAND gate
  2. BXOR gate
  3. COR gate
  4. DNOR gate

Correct answer

A. NAND gate

Step-by-step solution

From the given truth table, the output Y is 0 only when both inputs A and B are 1 . For all other combinations of inputs, the output Y is 1 . This is the exact complement of an AND gate, where the output is 1 only when both inputs are 1 . The Boolean expression for this truth table is Y = A B , which corresponds to a NAND gate. Answer: NAND gate
