Question

Which of the following is the logic circuit for Boolean expression A.B + C.D’ ?​

Answer 1

Answer:

Option (A)

Explanation:

Break the expression in two parts, A.B and C.D' these two parts are connected with a + whose binary equivalent is OR gate.

Therefore,

A.B  OR C.D'.

Now working on each expression separately,

• A.B: Clearly A and B are connected by an AND gate.
• C.D' : C and D' are connected by AND gate and to get D', D must've been connected to a NOT gate.

Using this final expression becomes,

(A AND B) OR (C AND (NOT D))

The circuital equivalent of this expression is shown in option (A).
