I am going through a past paper for an upcoming exam and I want to check that I am approaching this question correctly. H(s) = 1/(s2 + 8485.28s + 36x10-6) Calculate and plot frequency response for 0 rad/s, 500 rad/s, 1000 rad/s and 10000 rad/s. I am under the impression that the 's' term can be replaced with jω which gives: H(s) = 1/(jω2 + 8485.28jω + 36x10-6) where ω is the frequency. I then replace jω with the the frequencies given above. Is this correct?
