A JK flip-flop has the below truth table. Implement a JK flip-flop with only a D-type flip-flop and gates. Note: Qold is the output of the D flip-flop before the positive clock edge.

module top_module (
    input clk,
    input j,
    input k,
    output Q); 
    //Q(~j)(~k)+
    wire d;
    assign d=(Q&(~j)&(~k))|(j&(~k))|(j&k&(~Q));
    always@(posedge clk) begin
        Q<=d;
    end
endmodule
