17. Design an SR flip-flop circuit with asynchronous Set (S) and Reset (R) inputs using NOR gates. The circuit should operate as follows: If S=1 and R=0, the flip-flop should be set (Q=1,Q=0). If S=0 and R=1, the flip-flop should be reset (Q=0,Q=1). If both S and R are 0 , the flip-flop should maintain its previous state. If both S and R are 1, the flip-flop should toggle its state (Q=Q). Use NOR gates in your design. Hint: Design the truth table and show the next state
