For the following circuit and given inputs A and B , choose the correct option for output ‘ Y ’

Step-by-step solution

The signal A is given to a NOR gate and B is given to an OR gate. The output of these two signals is given to a NAND gate. Using the laws of Boolean algebra, Y = A   · B ¯   = A + B ¯ . Analysing from the input graphs, one can see, t 1 - t 2 :   A = 0 ,   B ¯ = 0 ,   Y = 0 t 2 - t 3 :   A = 1 ,   B ¯ = 0 ,   Y = 1 t 3 - t 4 :     A = 0 ,   B ¯ = 1 ,   Y = 1 t 4 - t 5 :     A = 1 ,   B ¯ = 0 ,   Y = 1 t
