4.(24%) This problem considers six transfer functions G1 = 1/(s+1), G2 = 2/(s+2), G3 = 1/(s²+s+1),G4 = 3(s²+s+3), G5 =2/(s²+3s+2), and G6 = (s+10)((s²+s+10). Their step responses (AI, A2 , A6) are amplitude spectra (B1, B2 , B6) are given in the figures shown in the following pages. Please pair each of the transfer functions to one of the step responses and one of the amplitude spectra.(That is, if you think A1 is the step response of G1 and B1 is the amplitude spectrum of GI, write your answer for G1 as G1-A1-B1. Please present your answers in this way for all the six transfer functions considered in this problem.
