Question -
To get an output Y = 1 from the circuit shown in figure the inputs A, B and C must be respectively
Options:
A .  1, 0, 1
B .  1, 1, 0
C .  0, 1, 0
D .  1, 0, 0
Answer: Option A : A The output of OR gate is Y’ = (A + B) The output and AND gate is Y = Y’ . C = (A + B) . C IfA = 1, B = 0, C = 1, they Y = (1 + 0). 1 = 1
