The circuit in Figure 14–9

(b) has a high-pass transfer function given in Eq. (14–11) and repeated below

In Section 14–2, we developed equal-element and unity-gain design methods for this circuit. This problem explores an equal-time constant design method. Using R1C1 =R2C2 and μ = 2, develop a method of selecting values for C1, C2, R1, and R2. Then select values so that the filter has a cutoff frequency of 500 krad=s and a ζ of 0.25. Use MATLAB to plot the filter’s Bode diagram.
