    You literally just pulled a bunch of new things out of the air without explaining their background. Where did h(t) come from and why is it a transfer function? What is a transfer function? You applied this property of LaPlace , L{f(t-a)}=L{f(t)}×e^-as, and didn't explain how you got that or prove it's true. You didn't explain why H(s) = Y(s) / X(s). You also just randomly said the inverse LaPlace of e^(as) is d(t-a)...no explanation of how you know that or where it came from. Most of your videos are really good. This one was horrible.

    Laplace? More like “this is the place”…for learning. Thank you for uploading these very informative lectures!

      @@omarilyas6103 Haha yeah I know, but I still like posting puns because it's led to some really cool conversations! Plus I think it drives up engagement on videos, and I try to support the channels that way. Another strategy I've adopted is replying to comments that mention an upcoming test, and asking how it went. I've gotten a few conversations out of that as well.

    U(t) is step signal that limit you used in example but you said Impulse response used to get system response. May be it's because of Laplace integration we have to take during convert "t" to "S" domain. point me if i'm incorrect.

      It is not split system. It's TIV system.
      y(t)=a(t)x(t-1)+b(t)x(t+1)
      a(t)=1 t0
      this is split. here we define coefficient a(t) and b(t).
