Electronic Devices Question 272

Question: For the given combination of gates, if the logic states of inputs A, B, C are as follows A = B = C = 0 and A = B = 1, C = 0 then the logic states of output $D$ are

[AMU 1998]

Options:

A) 0, 0

B) 0, 1

C) 1, 0

D) 1, 1

Show Answer

Answer:

Correct Answer: D

Solution:

The output D for the given combination

$D = \overset{―}{(A + B) . C} = \overset{―}{(A + B)} + \bar{C}$

If $A = B = C = 0$ then $D = \overset{―}{(0 + 0)} + \bar{0} = \bar{0} + \bar{0} = 1 + 1 = 1$

If $A = B = 1$ , $C = 0$ then

$D = \overset{―}{(1 + 1)} + \bar{0} = \bar{1} + \bar{0} = 0 + 1 = 1$
