Frequency response from transfer function, Process control

Question:Frequency response from transfer function, Process control

Hi all,

I have a simple transfer function like

$G=\frac{0.1(s+0.2)\cdot e^{-4.5s}}{(s+0.5)(s+0.4)(s+0.1)(s+0.02)}$

I want to calculate the amplitude ratio and the phase shift.

Without maple I would set s=I*omega and solve for real and imaginary part to obtain the phase shift and amplitude ratio.

$AR=\sqrt{R^2+I^2}$

$\phi=arctan(I/R)$

Is there any possibility to do that in Maple more easily?
