| Question 87 |
Consider the following circuit.
Which one of the following is TRUE?
| f is independent of X
| |
| f is independent of Y | |
| f is independent of Z | |
| None of X, Y, Z is redundant |
Question 87 Explanation:
f(X,Y,Z) = ((XY’)’ (YZ))’
= ((X’+Y) YZ)’
= (X’YZ + YZ)’
= ((X’+1) YZ)’
= (YZ)’
= ((X’+Y) YZ)’
= (X’YZ + YZ)’
= ((X’+1) YZ)’
= (YZ)’
Correct Answer: A
Question 87 Explanation:

= ((X’+Y) YZ)’
= (X’YZ + YZ)’
= ((X’+1) YZ)’
= (YZ)’
