12–66 Consider the gain plot in Figure P12–66.

(a) Find the transfer function corresponding to the straightline gain plot.

(b) Hand-draw a straight-line plot of the phase.

(c) Use MATLAB to plot the Bode magnitude and phase of the transfer function.

(d) Compare the straight-line gain and phase with the actual responses (from MATLAB) at ω = 100 and 500 rad=s.

(e) Design a circuit that will realize the transfer function found in part (a).

(f) Use Multisim to verify your circuit design.
