Derive the Boolean expression for the logic circuit shown below:
  1. AC(A + B)DE
  2. B[C(A + B)D + E′]
  3. C[[C(A + B)D]E′]
  4. DMore than one of the above
  5. ENone of the above
Show answerHide answer

Correct answer: (A) C(A + B)DE

Explanation

The circuit gives A + B from the OR gate, then three AND gates in turn multiply it by C, D and E. So Y = C(A + B)DE, with E not inverted.
