Question

In the following combinations of logic gates, the output of A, B, and C are respectively

	A	B	C
(a)	0	0	0
(b)	0	1	1
(c)	1	0	0
(d)	1	1	1

Answer 1

Answer is : (b)

In case of AND gate

output (Y) = (Input A) ⋅ (Input B)

⇒ Y = A . B

In case of NAND gate

Y = \(\overline{A.B}\)

In case of NOR gate

Y = \(\overline{A+B}\)

In case of NOT gate

Y = \(\overline{A}\)

(a) Here A = 0.0 = 0

(b) B = \(\overline{0.1}\) = 1

(c) C = 1.0 = 1
