Question

Problem-1 (60 pts) Manually sketch (i.e. don't use Matlab) the frequency responses (gain and phase Bode plots in logarithmic domain) of the following transfer functions (Hint: Clearly identify the poles and zeros, find the contributions from these poles and zeros over the plots, obtain independent gain and phase contributions and combine them in single phase and gain plots). For the plotting, one can use an empty log-log graph, make the hand drawing, scan and add the hand-plotted graph to the report 2+5s+4 s3+4s2+8s+8 3+2s2-5s+20 b) G(S) = s4+53 +3s2 +10s +10
