The circuit shown in the following figure realizes the function
(A) (( A + B )\’ +C ) ( D\’E\’ )
(B) (( A + B )\’ + C ) ( DE\’ )
(C) ( A + ( B + C )\’ ) ( D\’E )
(D) ( A + B + C\’ ) ( D\’E\’ )
Answer: (A)
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\')
Option (A) is correct.
