In a broad solution, you need to reverse the convolution of your system’s output.

Assuming it’s a linear continuous system, and it’s Single Input and Single Output (SISO), you do the Laplace transform of the signal L{y(t)}=Y(s), obtain the Laplace transform of the input L{x(t)}=X(s), and then obtain the transfer function of the system: H(s)=Y(s)/X(s), you must be aware the transfer function of the step is 1/s, therefore: H(s)=Y(s)/(1/s) => H(s)=sY(s), then you do the inverse Laplace transform: L-¹{H(s)}=L-¹{sY(s)}, which, depending on your system, may require partial fraction expansion. By the end you have h(t) (got a bit lazy here since y(t) is not known, but the step function is very well known).

Of course I made a bunch of assumptions about your system, if your system has discrete steps, the Z transform is of interest, with its own caveats mind you. Then there are filters and other numerical approximations for a reverse convolution.

Even it had found links, finding a link and defining HTTPS, HTTP, and SSL is not helpful.

Maybe the comment wasn’t synchronized with your instance yet, and I’m not sure if the bot identified a link like this or a link like https://google.com/, where in the markdown description they added the HTTPS explicitly.

And I don’t know if the bot suffers from the Scunthorpe problem, i.e. dumb bot.

But they are in this thread, someone directly mentioned Git, both HTTP and HTTPS are mentioned directly in links description, and finally SSL is mentioned by the bot itself when explaining HTTPS.
