29. One Shot Pulse

How do you plan to solve it?

module rise_pulse(
  input  wire clk,
  input  wire rst,      // synchronous active-high reset
  input  wire sig_in,
  output reg  pulse
);
  reg prev;             // previous sampled value of sig_in

  always @(posedge clk) begin
    pulse <= (rst)? 1'b0 : ~prev & sig_in;
    prev <= (rst)? 1'b0 : sig_in;
  end
endmodule
