Sketch the straight-line approximation Bode plot diagrams (magnitude and phase) 110s for H[s] You might want to examine Examples E.1 and E.2 in (s+10)(s+100)´ the textbook. Based on your straight-line Bode plot sketch, answer the following questions. The questions are: a. Identify the transfer function written in time constant form. b. The phase of H[s] at low frequencies is? c. The magnitude plot has what slope at low frequencies? d. The magnitude plot has what slope at high frequencies? e....

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...
Problem: A. For every Bode magnitude plot, do the following: (a)Find the Bode gain, K. (b)List the corner frequency for each factor. (c)Draw the straight line Bode magnitude plot for each factor, using the correct slope. (d) Carefully combine the plots into a composite straight line plot, using graphical addition at (e) (f) the corner frequencies. Use a heavy line for this composite plot. Go back and add the appropriate corrections at corners (±3 dB for simple poles/zeros) By hand,...
