The output Y of the given logic circuit is
Options
- A(A B) + (C B)
- B(A + B) (B C)
- C(A B) + (B + C)
- D(A + B) + (B + C)
Correct answer
C. (A B) + (B + C)
Step-by-step solution
The given logic circuit consists of three gates. The upper gate is a NAND gate with inputs A and B . Its output is A B . The lower gate is a NOR gate with inputs B and C . Its output is B + C . The final gate is an OR gate which takes the outputs of the NAND and NOR gates as its inputs. Therefore, the final output Y is given by the logical OR operation of these two intermediate outputs: Y = A B + B + C Answer: (A B) + (B + C)
