    Hi,
    I have done two tasks. I dont know if they are correct, so I ask for a quick overview.
    Here we go:
    sketch the system response of the unit step function u(kT)

    Mine solution:

    That would be option a) and I think it's good. Its not problem to draw a graph from that table.


    b.)

    I'm not sure about this option under b.),actually I think that professor said that we need to have z^-1 in the numerator of the H(z) , and in my case H(z) is (1/(1-z^-1)). Can any of you guys take a look and give some notes/tips.
