What is a problem of my graph?(frequency response)

  1. Nov 23, 2016 #1
    I have drawn a bode plot(freauency response), but it is not the same with one which is attatched in paper.

    Using this data, I have drawn the graph using matlab.
    I just put data into second order vibratoion system which is given in the paper(eq 18)

    Peak location of graph in paper is just in front of 10^3 but the other is just in front of 10^4.
    What is wrong?

    I think you are plotting vs ω, and the paper is plotting vs f, so there is a factor of 2π difference.
