to get output 1 for the following circuit the correct choice for the input is
Answers
A = 1, B = 0 and C = 1 !
Explanation:
Options should be :
a ) A = 1, B = 0,C = 0
b ) A = 1, B = 1, C = 0
c ) A = 1, B = 1, C = 1
d ) A = 0, B = 1,C = 0
Consider the given figure,
the resultant boolean expression of the above logic circuit will be
Y = ( A + B ) × C
Now let's try with inputs A,B and C are given in the options and let see, which one of the them will give output 1 at Y
• If A = 0, B = 0, C = 0
=> Y = ( 0+0 ) × 0
=> Y = 0
• If A = 1, B = 1, C = 0
=> Y = ( 1+1 ) × 0
=> Y = 1 × 0
=> Y = 0
• If A = 1, B = 1, C = 1
=> Y = ( 1+0 ) × 1
=> Y = 1 × 1
=> Y = 1
• If A = 0, B = 1, C = 0
=> Y = ( 0+1 ) × 0
=> Y = 1 × 0
=> Y = 0
So we have seen that among the given options, only option (c) is correct choice, i.e.
Output option (c) is correct choice, i.e.
Output Y = 1 only when inputs A = 1, B=0 and C=1 !
