Question 6
|
The logic expression for the output of the circuit shown in the figure is
|
A’C’ + B’C’ + CD
|
|
|
AC’ + BC’ +C’D
|
|
|
ABC + C’D’
|
|
|
A’B’ + B’C’ + C’D’
|
|
|
None of the above
|
Question 6 Explanation:
[((A+B)’+c)’+(c+d)’]’
=((A+B)’+C)(C+D)
=(A’B’+C)(C+D)
=A’B’C+C+A’B’D+CD
=(A’B’+1+D)+A’B’D
=A’B’D
Note: They given wrong options.
=((A+B)’+C)(C+D)
=(A’B’+C)(C+D)
=A’B’C+C+A’B’D+CD
=(A’B’+1+D)+A’B’D
=A’B’D
Note: They given wrong options.
