In the following digital logic circuit, the output Y will be ' 1 ' for inputs

Options

  1. AA =0, ~B =0
  2. BA =0, ~B =1
  3. CA =1, ~B =0
  4. DA =1, ~B =1

Correct answer

D. A =1, ~B =1

Step-by-step solution

There are two NOR gates, one NOT gate, and one NAND gate. Output of NAND gate: A B Output of NOT and NOR Gate: A + B Final output: ( A B )+( A + B ) So, the output Y is 1 only if the input A and B is 1. aligned & A =1 & ~B =1 & Y = 1 1 + 1 +1 & Y =1 aligned
