"ROC must contain unit circle", that just works like a charm, thank you Sir!

Holy shit, this is amazing. Been trying to grasp these concepts for so long, everything clicked just right with this video

This video is great, thank you for a very clear explanation that helped me understand how to perform inverse z-transforms a lot better. I wonder why this video hasn't got many views?

Great help, but man do I hate this crap. I'm not going into DSP, and yet I have to know this. So dumb!!!!

Please what if the poles of the system are say 0.4 and 0.8. Drawing both pole circles, the unit circle will be outside the two pole circles instead of within them like example above. Does a stable impulse ROC exist?

Thank you sir...if they give h (n) how to find stability...

if A and B can only exist at z = -1.4 and 0.6, why can you just put in A and B for the general H(z) equation?

for z>0.6 is the z transform u (n-1) and not u(n)
