Consider the following circuit
The function by the network above is
Correct Answer: B
Question 80 Explanation:
[ ((AB)’ E) + (EF) + (F(C+D)’) ]’
= ((AB)’ E)’ (EF)’ (F(C+D)’)’
= (AB+E’)(E’+F’)(F’+C+D)
= (ABE’ + ABF’ + E’ + E’F’)(F’+C+D)
= (ABF’+ E’(AB+1+F’))(F’+C+D)
= (ABF’+E’) (F’+C+D)
= ((AB)’ E)’ (EF)’ (F(C+D)’)’
= (AB+E’)(E’+F’)(F’+C+D)
= (ABE’ + ABF’ + E’ + E’F’)(F’+C+D)
= (ABF’+ E’(AB+1+F’))(F’+C+D)
= (ABF’+E’) (F’+C+D)
(AB)’E + EF + (CD)’F
(E’ + ABF’)(C+D+F’)
((AB)’+E)(E’+F’)(C+D+F’)
(A+B)E’ + (EF)’ + CDF’
