Homework Help: Sketch and Determine the Transfer Function From Its Poles

  1. Oct 6, 2011 #1
    1. The problem statement, all variables and given/known data
    If a transfer function has poles at (-1,2) and (-1,-2) and a zero at (0,0):

    a) Sketch |H(jω)| on the interval 0≤ω≤10.
    b) If |H(jω)| = 1, what is the approximate value of |H| at its highest point?

    2. Relevant equations

    3. The attempt at a solution

    I think I have the sketch down, but I'm really confused on finding the transfer function. I know that it's the distance to the zeros over the distances to the poles, but I just really don't understand how to find them.
