The two combinations of NAND gates shown in the figure are equivalent to (i) (ii)
Options
- A(i)-Or gate, (ii)-AND gate
- B(i)-AND gate, (ii)-NOT gate
- C(i)-NOT gate, (ii)-AND gate
- D(i)-AND gate, (ii)-OR gate
Correct answer
A. (i)-Or gate, (ii)-AND gate
Step-by-step solution
The output of combination of NAND gate shown in circuit diagram (i) is given as aligned & C= A B = A + B [ x y = x + y ] & C=A+B= Output of OR gate aligned The output of combination of NAND gate shown in circuit diagram (ii) is given as Fig. (ii) C= A B =A B= Output of AND gate
