Justify the output wavefrom (y) of the OR gate for input and as gives in Fig.

Explanation

From the given wavefrom, we note the followings:
`{:("Time interval",Input A, Input B, Output y),("For time"t lt t_(1),0,0,0),("For time"t_(1) "to" t_(2),1,0,1),("For time" t_(2) "to" t_(3),1,1,1),("For time" t_(3) "to" t_(4),0,1,1),("For time" t_(4)"to" t_(5),0,0,0),("For time" t_(5) "to" t_(6),1,0,0),("For time" t gt t_(6),0,1,1):}`
Since the output is 1 in level when if one or more input assume 1 in level), so the Boolean expression A+B=y is satisfied, which is for OR gate.
