A) \[(\overline{X}\,.\,\,\overline{Y})\,.\,\,Z\]
B) \[(X\,.\,\,Y)\,.\,\,Z\]
C) \[(X\,+\,Y)\overline{Z}\]
D) \[(\overline{X}\,.\,\overline{Y}+\overline{Z}\]
Correct Answer: A
Solution :
We can realise the combination as shown below. Gate-1, is OR gate while gate-2 is AND gate. Output of OR gate, \[{{W}_{1}}=\overline{X}+\overline{Y}\] Thus, output of AND gate, \[W={{W}_{1}}\,.\,\,Z\] \[=(\overline{X}+\overline{Y})\,.\,\,Z\]You need to login to perform this action.
