For the process described by the transfer function

(a) Find two second-order-plus-time-delay models that approximate G(s) and are of the form

One of the approximate models can be found by using the method discussed in Section 6.3; the other, by visual inspection of the frequency responses of G and G.

(b) Compare all three models (exact and approximate) in the frequency domain and also by plotting their impulseresponses.
