Correct answer: C. 1, 1, 1, 0

Look at the above circuit, the value of

P

can be found by the idea of AND gate,

P = A \cdot B

and the value of

Q

, can be calculated by the idea of OR gate,

Q = A + B

. Then expression for

Y

can be taken by the idea of NAND gate,

⇒ Y = \overset{¯}{P \cdot Q}

by the idea of Demorgan's theorem,

Y = \overset{¯}{P} + \overset{¯}{Q} = \overset{¯}{A} + \overset{¯}{B} + \overset{¯}{A} \cdot \overset{¯}{B}

In the following logic circuit the sequence of the inputs A, B are ( 0, 0 ) , ( 0, 1 ) , ( 1, 0 ) and ( 1, 1 ) . The
