What is a interlaced zero in transfer function?

  1. Sep 25, 2016 #1
    A reading assignment I have read said "By adding a direct feed-through to a
    collocated system, the transfer function can be modified from containing
    resonant poles followed by interlaced zeros, to zeros followed by interlaced
    poles." I don`t konw what this sentence mean. What is the resonant poles followed by interlaced zeros and resonant poles followed by interlaced zeros?
    (I know that In feedback system, stability can be determined by location of ploes. And if every pole exists in real negative axis, we can call the system stable.)

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
