For a D flip-flop with inputs \( \mathrm{A}, \mathrm{B} \) and output Y , which expression is true assuming Y is initially 0 ? When \( \mathrm{A}=1 \) and \( \mathrm{B}=0 \), and CLK \( =1 \) then, \( \mathrm{Y}=1 \) When \( \mathrm{A}=1 \) and \( \mathrm{B}=1 \), and \( \mathrm{CLK} \uparrow \) then, \( \mathrm{Y}=1 \) When \( \mathrm{A}=0 \) and \( \mathrm{B}=0 \), and \( \mathrm{CLK} \uparrow \) then, \( \mathrm{Y}=1 \) When \( \mathrm{A}=0 \) and \( \mathrm{B}=1 \), and \( \mathrm{CLK} \uparrow \) then, \( \mathrm{Y}=1 \)

Step 1
The circuit consists of an OR gate followed by a D flip-flop. The inputs to the OR gate are A and B, and the output of the OR gate is connected to the D input of the flip-flop. Show more…
