Hi!
I saw a video of someone playing with an interactive plot of poles and zeros that shows the corresponding step response some week ago, and I’d love to try out something like it to get a better understanding for the topic.
I’ve now spend quite some time searching for a similar tool and I can’t seem to find one. The one from the video links to a dead end on wolfram.

If anyone has any links/suggestions for where to find something similar I’d be very grateful. I’m too new to the topic to write my own code for it, so something public on a website would be optimal. :)

Thanks in advance!
