Question 2
|
The circuit shown in the following figure realizes the function
|
(( A + B )’ +C ) ( D’E’ ))
|
|
|
(( A + B )’ + C ) ( DE’ ))
|
|
|
( A + ( B + C )’ ) ( D’E )
|
|
|
( A + B + C’ ) ( D’E’ )
|
Question 2 Explanation:
The given function is equivalent to the following expression:
Y = (((A + B)’ + C)’ + ((D + E)’)’)’
Y = ((A + B)’ + C)’)’ . (D + E)’
Y = ((A + B)’ + C) (D’E’)
Y = (((A + B)’ + C)’ + ((D + E)’)’)’
Y = ((A + B)’ + C)’)’ . (D + E)’
Y = ((A + B)’ + C) (D’E’)
Correct Answer: A
Question 2 Explanation:

Y = ((A + B)’ + C)’)’ . (D + E)’
Y = ((A + B)’ + C) (D’E’)
Y = (((A + B)’ + C)’ + ((D + E)’)’)’
Y = ((A + B)’ + C)’)’ . (D + E)’
Y = ((A + B)’ + C) (D’E’)
