| 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
