45. Signed vs Unsigned Compare

How do you plan to solve it?

/*Write your code here*/
module signed_thresh (
    input [7:0]sample,
    input [7:0]thresh,
    output reg gt_unsigned,
    output reg gt_signed
);
always @(*) begin
    if(sample>thresh)begin
        gt_unsigned = 1;
    end
    else gt_unsigned = 0;

    if ($signed (sample) > $signed (thresh))begin
        gt_signed = 1;
    end
    else gt_signed = 0;
end
endmodule
