From 0 to $t_{1}$
$A=1, B=1, \text { so } Y=1$
From $t_{1}$ to $t_{2}$
$A=0, B=0, \text { so } Y=0$
From $t_{2}$ to $t_{3}$
$A=1, B=0, \text { so } Y=0$
From $t_{3}$ to $t_{4}$
$A=0, B=1, \text { so } Y=0$
From $t_{4}$ to $t_{5}$
$A=1, B=1, \text { so } Y=1$
From $t_{5}$ to $t_{6}$
$A=0, B=0, \text { so } Y=0$
