Question

Consider this Bode Magnitude plot and its slope transitions. Find the transfer function for this Bode plot. 

ζ  peak (dB)
0.001 54
0.05 20
0.1 12
0.25 6
0.5 0
1 -6

first redraw the diagram with all the asymptotes at the features where the slope transitions and label the slope. find a list of features of zeroes at s=? and poles at s=? where the slope transitions and the w range with w min being 1/10th of the smallest feature and w max being 10* the biggest feature in rad/s. Find the initial asymptote where the transfer function |T(jw)| w tends to 0 in the graph approximately and at wn and damping ratio. remember that 20 db/decade slope is like a 45 degree slope and that zeros give a positive slope and poles give a negative slope.
