    Hi, All:

    Could you please explain these integrators differece?

    1. 1/(1-z^(-1))
    2. z^(-1)/(1-z^(-1))
    3. Tz^(-1)/(1-z^(-1))

    Thanks a lot!

  2. it that a homework question?

    They are all the same, as 1, exept 2 has one sample period delay, and 3 has
    one sample period delay and a T times the output.

    Seems like homework...or if you're just learning on your own, I think
    you'll be better served by thinking it through yourself anyway. But
    here are a couple things to ponder:

    Think about where the poles and zeros are. What's the difference
    between 1 and 2--and what does that difference represent? (That is,
    in a block diagram representation, can you see a common block and a
    block that one has and the other does not? And what does that
    different block represent?)

    So, is 'boki' a bot? An 'automatic' TA? An autotroll?

    Whats the deal? The questions seem varied in level and, well, oddly worded.

  5. worded.

    Oddly spelled, too.
