(a) A control system is modelled by the transfer function s G(s) = s+5 (1) Find its analytical expressions of both magnitude frequency response and phase frequency response. (ii) Let G2(s) = Ks where K is a positive gain. Using the results obtained in (i), determine the analytical expressions of both the magnitude and phase frequency responses of G (s)G2(s). Then, briefly discuss how the value of K affects the magnitude and phase frequency responses of G(s)G2(s), respectively. [8 marks]
