A proper combination of 3 NOT and 1 AND gates is shown. If A = 0, B = 1, C = 1 then the output of this combination is
A)1
B)zero
C)not predictable
D)None of these
Correct Answer:
B
Solution :
The simplified circuit is shown in figure below. So, output \[Y=\bar{A}.\bar{B}.\vec{C}\] If \[A=0,\,B=1,C=1\] \[\therefore \] \[Y=\bar{0}.\bar{1}.\bar{1}=1.0.0=0\]
