The output of the logic circuit shown in figure will be

Options

  1. AX = A.B
  2. BX = A.B
  3. CX = A + B
  4. DX = A + B

Correct answer

B. X = A.B

Step-by-step solution

The given logic circuit consists of two NAND gates. The output of the first NAND gate with inputs A and B is: Y = A B This output Y is connected to both inputs of the second NAND gate. A NAND gate with its inputs tied together acts as a NOT gate. The final output X is: X = Y Y = Y Substituting the value of Y : X = A B = A B Thus, the circuit acts as an AND gate. Answer: X = A.B
